In 1909 Steinert and colleagues first clearly described the “classic”

type of myotonic dystrophy which was called Steinert’s disease (OMIM 160900). The gene defect responsible for myotonic dystrophy described by Steinert was discovered in 1992 and found to be caused by expansion of a CTG repeat in the 3′ untranslated region of DMPK, a gene encoding a protein kinase (2-4). Subsequently, in 1994, a different multisystemic disorder was described with Inhibitors,research,lifescience,medical dominantly inherited myotonia, proximal greater than distal weakness, and cataracts but lacking the gene defect responsible for Steinert’s disease (5-7). In Europe, the disease was termed proximal myotonic myopathy (PROMM, OMIM*160900) (6) or proximal myotonic dystrophy (PDM) (7) while in the United States was termed myotonic dystrophy with no CTG repeat expansion or myotonic dystrophy type 2 (DM2) (5). Later studies demonstrated that many of the families identified as having myotonic dystrophy type 2, PROMM or PDM had the same disease, a disorder caused by an unstable tetranucleotide CCTG Inhibitors,research,lifescience,medical repeat expansion in intron 1 of Zinc finger protein 9 gene (ZNF9) mapped to 3q21.3 (8, 9). Due to the existence of different types of myotonic dystrophy, the International Myotonic Dystrophy Consortium developed a new nomenclature and guidelines for DNA testing

(10). The Steinert’s disease that results from an unstable trinucleotide repeat expansion on chromosome 19, is now termed myotonic dystrophy Inhibitors,research,lifescience,medical type 1 (DM1). Patients with the clinical picture of myotonic dystrophy type 2/proximal myotonic Inhibitors,research,lifescience,medical myopathy, who have positive DNA testing for the unstable tetranucleotide repeat expansion on chromosome 3, are now classified as having myotonic dystrophy type 2 (DM2) (5, 11-12). Although DM1 and DM2 have similar symptoms, they also present a number of very dissimilar features making them clearly separate diseases (Table 1). Table 1. see more Comparison of clinical manifestations between DM1 and DM2. Myotonic Dystrophy type 1 Clinical features Myotonic dystrophy type 1 is the most common inherited muscular dystrophy Inhibitors,research,lifescience,medical in adults with

an estimated prevalence of 1/8000. DM1 is characterized by the phenomenon of anticipation, by which the disease has an earlier onset and more severe course in subsequent generations. Patients with DM1 can be divided into four main categories, each presenting specific clinical features and tuclazepam management problems: congenital, childhood-onset, adult-onset, and late-onset/asymptomatic. Table 2 summarises these subtypes. Table 2. Summary of myotonic dystrophy type 1 phenotypes, clinical findings and CTG length. Congenital DM1 Congenital DM1 (CDM) shows a distinct clinical phenotype with distinct clinical features, therefore it is to be considered a severe early form of ‘classical’ DM1. CDM often presents before birth as polyhydramnios and reduced fetal movements. After delivery, the main features are severe generalized weakness, hypotonia and respiratory involvement.

Over an affected individual’s lifetime, costs of care can reach about $3.2 million, while the annual cost to society is an estimated $35 billion.1 Such burdensome costs combined with new high estimates in prevalence—the newest numbers place the developmental disorder at 1 in 88 children2—call for a need to fully understand and to develop new treatments for autism. Treatment for ASD has shown uneven efficacy, and no treatment to date

has demonstrated the ability to alleviate Inhibitors,research,lifescience,medical the core social deficits. While the high-functioning spectrum of ASD has shown promising and hopeful response to behavioral treatments, a sizable cohort, predominantly lower-functioning and/or with comorbid Inhibitors,research,lifescience,medical intellectual disability, has not demonstrated significant treatment gains.3 For this latter group of patients, the need to develop new treatment paradigms is critical. Understanding the neurodevelopment

mechanisms gone awry may provide crucial insights into the underlying pathobiology of autism and identify novel, effective treatment methods. An essential step is to determine what aspects of brain development and function are impaired in autism. Forward genetics, a process that identifies putative genes or gene networks, allows researchers to identify mutations, sometimes specific molecules, and perhaps Inhibitors,research,lifescience,medical converging mechanisms involved in autism.4 One important question researchers should attempt to answer is: Can mutation discoveries Inhibitors,research,lifescience,medical lead us to specific step(s) that are perturbed during neurodevelopment? By answering this question, researchers may be able to identify

distinct neurodevelopmental processes responsible for autistic subtypes that may Inhibitors,research,lifescience,medical allow for targeted treatments of autistic symptoms. In this review, we will argue that genetic studies in particular have helped us pinpoint a small number of neurodevelopmental steps that are generally involved in autism to those of the late steps of Selleckchem ABT199 neurodevelopment, that are primarily involved in the development of neurocircuitry, namely axon and dendrite growth and arborization, and also experience-dependent synapse modification. Human brain development and structural brain differences in autism In contrast to the >22 000 genes in the human genome and steep number of molecular mechanisms within a functioning and differentiating cell, the Sclareol number of steps involved in human brain development are relatively few and finite. Eleven processes are conceptualized in Figure 1. Essentially, we can divide these developmental stages of brain development into two categories: fetal and postnatal. Fetal brain development is largely experience-independent and begins with neural tube formation and patterning, and neurogenesis whereby neural progenitor cells proliferate and give rise to neurons of the brain.

They also agree that many intellectual abilities tend to be positively correlated, although they disagree as to just how wide-ranging these abilities

are. Beyond that, the consensus seems to diminish. At one time, intelligence research consisted primarily of statistical analyses of individual differences in scores on intelligence tests. Today, in addition to such psychometric research, intelligence is also being studied by cognitive psychologists, neuroscientists, cultural psychologists, and many others. Inhibitors,research,lifescience,medical Acknowledgments The Ribociclib supplier sections on genetic and heritability studies of intelligence and on racial differences in intelligence draw on collaborations with Elena Grigorenko, Kenneth Kidd, and Steven Inhibitors,research,lifescience,medical Stemler.
This brief review will focus on rodent (rat and

mouse) models of anxiety disorders. There are of course models of anxiety disorders in other species, including nonhuman primates,1 but rat and mouse models are byfar the most commonly used in the current preclinical and psychiatric (genetic) research. Our aim is not to present an exhaustive view of all existing models, but to discuss Inhibitors,research,lifescience,medical some conceptual issues related to these models. A first and important issue is whether various animal species can really be used as “models” of human pathologies, given the highly subjective nature of anxiety. Do animals experience something like human anxiety, Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical and how can we measure it, since we cannot “think like a rat”?2 We will argue that, as mentioned by many authors, the behavioral responses and brain mechanisms associated with an “anxious state” are so essential for survival that they must have

evolved very early in the development of nearly mammalian species and are probably highly conserved—the phylogenetic argument.3 In view of the relationship between anxiety and coping styles, or of the pivotal role of fear-conditioning processes (to be developed in the following sections), it is not unlikely that some form of anxiety exists in other vertebrate classes or lower organisms; even primitive ones have a capacity to detect danger and react to threat.4 This may offer new opportunities to design as-yet unexpected models.5-8 The probability of finding the various emotional responses and “logistic systems” involved in anxiety across phyla is discussed in a recent review.

19,20 Markon et al21 conducted a meta-analytic factor analysis of numerous measures of normal and abnormal personality representing the models of Clark,18 Livesley,11 and others, and reached the conclusion that all of the alternative models are indeed well integrated within a common, integrative, five-factor structure that that they indicated ”strongly resembles the Big Five Inhibitors,research,lifescience,medical factor

structure“ (p 144). Although DSM-5 is likely to keep the ten personality disorder classification system that appeared in DSM-IV, a new dimensional model of personality pathology classification will appear in Section 3 of the new manual; this section will include conditions and classifications that are in need of further study before being formally adopted. Section 3 of DSM-5 will include a five-domain Inhibitors,research,lifescience,medical dimensional model that aligns closely with the FFM,5,22 with each broad domain further differentiated into more specific traits that are included within the diagnostic criterion sets for the personality disorder categories, selleckchem consistent with the FFM diagnosis of personality disorder, proposed for the next edition of the diagnostic manual. The purpose of this paper is to provide a brief overview of the FFM, compare it with the DSM-5 Section 3 dimensional trait model, and outline its potential

strengths and advantages as a dimensional model of personality and personality disorder. The five-factor model Inhibitors,research,lifescience,medical Most models of personality have been developed through the reflections of well-regarded theorists (eg, refs 10,15). The development of the FFM was more strictly empirical; specifically, through studies of the trait terms within different languages. This lexical paradigm was guided by the premise that what has Inhibitors,research,lifescience,medical the most importance, interest, or meaning to persons will be encoded within

the Inhibitors,research,lifescience,medical language. Language can be understood as a sedimentary deposit of persons’ observations over the thousands of years of the language’s growth and transformation. From this perspective, the most important domains of personality will be those with the greatest number of terms to describe and differentiate the gradations and variations of a particular trait, no and the structure of personality will be evident in the empirical relationship among these trait terms.23 The initial lexical studies were conducted on the English language, and these investigations converged onto a fivefactor structure,23 consisting of extraversion (versus introversion), agreeableness (versus antagonism), conscientiousness (or constraint), emotional instability (or neuroticism), and intellect (unconventionality or openness). Subsequent lexical studies have been conducted in Czech, Dutch, Filipino, German, Greek, Hebrew, Hungarian, Italian, Korean, Polish, Russian, Spanish, Turkish, and other languages, and the findings have supported reasonably well the universal existence of the five domains.

For cocaethylene (an adduct product of cocaine and ethanol), the upper bracket indicates the peak urine concentration in a controlled study of simultaneous cocaine and ethanol administration [46]. Figure ​Figure3A3A illustrates the low cross-reactivity of marketed cocaine metabolite immunoassays to all compounds except benzoylecgonine. Figure 3 Variability in sensitivity Inhibitors,research,lifescience,medical of marketed cocaine metabolite and opiate screening immunoassays. The plotted circles indicate the concentration of compound that produces equivalent reaction to 300 ng/mL Selleck GSI-IX benzoylecgonine (cocaine metabolite assays) or 300 ng/mL

… Molecular similarity also explains the generally low false positive rates for cocaine metabolite assays. In terms of similarity, benzoylecgonine Inhibitors,research,lifescience,medical has low structural similarity (Tanimoto similarity of 0.615 or lower) to common medications or illicit drugs. Despite being a local anesthetic (in addition to its other effects), cocaine has low structural similarity to other clinically important local anesthetics (e.g., bupivacaine, lidocaine, Inhibitors,research,lifescience,medical and procaine), which have Tanimoto similarities to benzoylecgonine of 0.377 or lower, effectively explaining why such compounds or their metabolites do not cause false positives on the currently available cocaine metabolite screening immunoassays (Additional file 1, tab F). Opiate assays Unlike barbiturate

and benzodiazepine screening immunoassays, where some manufacturers have used multiple Inhibitors,research,lifescience,medical drugs or drug metabolites as antigenic targets, all currently marketed opiate immunoassays use antibodies raised solely

against morphine (Additional file 1, tab T). Based on our similarity calculations, this strategy would be predicted to be effective for the sensitive detection of opiates and metabolites that are structurally very close to morphine, including codeine (Tanimoto similarity to morphine = 0.943), heroin (Tanimoto similarity = 0.857), 6-AM (main metabolite Inhibitors,research,lifescience,medical of heroin; Tanimoto similarity = 0.891), and hydromorphone (Tanimoto similarity = 0.873). In fact, the package insert data reveals this generally to be true with few exceptions (e.g., a few assays are less sensitive to hydromorphone than to codeine; Additional file 1, tab N; Figure ​Figure3B).3B). Currently marketed opiate immunoassays perform less well in their detection of oxycodone (Tanimoto similarity SB-3CT to morphine = 0.800) with 2 of 8 marketed assays being essentially insensitive to oxycodone and 3 additional assays only producing cross-reactivity equal to 300 ng/mL morphine at oxycodone concentrations of 16,000 ng/mL or greater (Additional file 1, tab N; Figure ​Figure3B;3B; Table ​Table1).1). These assays also respond weakly to oxymorphone (Figure ​(Figure3B),3B), itself a clinically used drug and also a main metabolite of oxycodone [47].

All subjects were compensated for participation. Informed consent was obtained prior to testing under supervision of the Columbia University Medical Center Institutional Review Board. Neuropsychological

examination A battery of neuropsychological tests was administered to all participants. Tests that putatively assess the following domains were selected; memory: three measures of immediate verbal memory from the selective reminding test (SRT; Buschke and Fuld 1974). Speed of processing: the digit symbol subtest from the Wechsler Adult Intelligence Scale–www.selleckchem.com/products/PD-0325901.html Version 3 (WAIS-3; Wechsler 1997), Trail Making Test A (Lezak et al. Inhibitors,research,lifescience,medical 2004), and the Stroop color naming condition (Golden 1975). General fluid ability: matrix reasoning, letter-number sequencing, and block design subtests from the

WAIS-3. Vocabulary: the vocabulary subtest from the WAIS-3, Wechsler Inhibitors,research,lifescience,medical Test of Adult Reading (Wechsler 2001), and American National Adult Reading Test (Grober and Sliwinski 1991). These Neuropsychological variables were reduced through confirmatory factor analysis (CFA) on a larger sample of 188 participants Inhibitors,research,lifescience,medical in neuroimaging studies in our laboratory. CFA was utilized to obtain the factor scores for the aforementioned cognitive domains. The a priori four-factor model of memory, speed of processing, general fluid ability, and vocabulary yielded acceptable fit statistics: root mean square error of approximation = 0.05, comparative fit index = 0.99; Tucker-Lewis index = 0.98. All indicator task loadings on their respective cognitive factors were

at or above Inhibitors,research,lifescience,medical 0.68. Factor scores were outputted from Mplus Version 6.12 (Muthen and Muthen 1998). Data acquisition Structural images were acquired using a 3.0 Tesla magnetic resonance scanner (Philips, Andover, MA). Structural image Inhibitors,research,lifescience,medical were obtained with T1-weighted turbo field echo (FE) high-resolution image with echo time (TE) = 2.98 msec; repetition time (TR) = 6.57 msec; flip angle = 8°; 256 × 256 matrix; in-plane voxel size = 1.0 × 1.0 mm; slice thickness = 1.0 mm (no gap); 165 slices. Functional images were acquired using the same 3.0 Tesla magnetic resonance scanner with a FE echo planar imaging (FE-EPI) sequence (TE/TR = 20/2000 msec; flip angle = 72°; 112 × 112 matrix; in-plane voxel size = 2.0 × 2.0 mm; Mannose-binding protein-associated serine protease slice thickness = 3.0 mm [no gap]; 37 transverse slices per volume), 6:1 Philips interleaved, in ascending order. Participants were scanned for 9.5 min, with instructions to rest, to keep their eyes open for the duration of the scan, not to think of any one thing in particular, and not to fall asleep. MRI data reconstruction Each subject’s structural T1 scans were reconstructed using FreeSurfer (http://surfer.nmr.mgh.harvard.edu/). The accuracy of FreeSurfer’s subcortical segmentation and cortical parcellation (Fischl et al. 2002, 2004) was reported to be comparable to manual labeling.

Dengue has become a major international health concern, with some countries, such as Brazil, experiencing annual epidemics [McBride and Bielefeldt-Ohmann, 2000; Schmidt, 2010; #Natural Product Library datasheet randurls[1|1|,|CHEM1|]# Barreto et al. 2011]. There are different forms and clinical manifestations Inhibitors,research,lifescience,medical of the disease, with the most severe being the life-threatening dengue hemorrhagic fever (DHF)/dengue shock syndrome [Onlamoon et al. 2010]. The most common manifestation of this disease, classic dengue fever, is a mild

febrile illness that is characterized by fever, musculoskeletal pain, severe headache, pain behind the eyes, nausea and vomiting, maculopapular rash, leucopenia and thrombocytopenia Inhibitors,research,lifescience,medical [WHO, 1997]. Severe thrombocytopenia is often present in DHF cases, but not in classic dengue fever, when just mild thrombocytopenia

generally occurs. Leucopenia, generally a consequence of neutropenia, is typical and generally found among patients with dengue as a mild reduction of white blood cell (WBC) count. However, there are also rare cases of severe neutropenia or life-threatening agranulocytosis [Insiripong, 2010]. The exact pathogenic mechanisms that lead to WBC alterations are not fully understood, but bone marrow suppression in dengue infection is well documented and probably Inhibitors,research,lifescience,medical has a major role in the hematologic alterations present among patients with dengue [Srichaikul and Nimmannitya, 2000]. Clozapine (CLZ) remains the most effective treatment for schizophrenia, Inhibitors,research,lifescience,medical but because of its poor side-effect profile, is generally used for patients who respond poorly to other antipsychotics [Tandon et al. 2007]. The side effects of CLZ, in particular neutropenia and agranulocytosis, continue to be a focus of concern during treatment with this antipsychotic, with an incidence of agranulocytosis of around 1% and of neutropenia of about 3%, with the highest risk within the first 6–18 weeks of treatment [Atkin Inhibitors,research,lifescience,medical et al. 1996]. Such a risk demands guarantees of safety during treatment with CLZ through close clinical followup and mandatory scheduled

hematologic screening [Novartis Pharmaceuticals Canada Inc., 2010] (Table 1). The occurrence of such complications during the treatment of patients whose condition has usually failed to respond to all other pharmacological alternatives may leave their psychiatrists without viable options for Tolmetin an effective treatment. Therefore, it is critical to understand the relevance of WBC alterations during dengue infection in patients with schizophrenia who are taking CLZ. Table 1. Clozapine hematological monitoring and appropriate management based on CBC results [Novartis Pharmaceuticals Canada Inc., 2010]. Materials and methods We are addressing this concern by presenting three cases of dengue infection in CLZ-treated patients with schizophrenia (Table 2).

the malignant cells, demonstrates disrupted renal tissue with lymphoma infiltrating between the tubules (Figure 4). Figure 2 High power image of peripancreatic tissue showing well preserved lymphomatous infiltrate, characterized by large cells with round nuclei and occasional prominent nucleoli Figure 3 An intermediate magnification of pancreas tissue demonstrates diffuse infiltration of lymphoma with near effacement of normal pancreatic architecture Figure 4 A kidney tissue Inhibitors,research,lifescience,medical section stained with antibody directed against CD20, highlighting the malignant cells, demonstrates disrupted renal tissue with lymphoma infiltrating between the tubules Discussion Extra-nodal involvement of non-Hodgkin’s lymphoma occurs in more than 50% of patients (1,2). The most frequent site is the gastrointestinal tract,

especially the stomach and small intestine (1-3). In contrast, pancreatic lymphoma is uncommon: Inhibitors,research,lifescience,medical less than 0.5% of pancreatic tumors are of lymphomatous origin, and only 0.2-2% of patients with non-Hodgkin’s lymphoma have pancreatic involvement at presentation (1-5). Most cases of pancreatic lymphoma are of Inhibitors,research,lifescience,medical the diffuse large B-cell type (1). The diagnosis of pancreatic lymphoma may be difficult, as symptoms, laboratory studies and imaging are often nonspecific (1,4). LDH can be elevated in 50% of cases and tumor marker CA 19-9 may occasionally be elevated (1). The most common presentation of pancreatic lymphoma is abdominal pain [83% Inhibitors,research,lifescience,medical of cases (4)], as well as weight loss, nausea and vomiting

(1). Typical B-symptoms of lymphoma, such as fever and night sweats, are uncommon (1). Pancreatic lymphoma is itself unusual, but pancreatic lymphoma presenting as acute pancreatitis is rare. To our Inhibitors,research,lifescience,medical knowledge, only twelve other cases of pancreatic B-cell lymphoma presenting as acute pancreatitis have been described (1-5). In contrast, pancreatic adenocarcinoma associated with pancreatitis is a well-documented phenomenon with up to 14% of cases of adenocarcinoma of the pancreas presenting as acute pancreatitis (6). The proposed mechanisms of pancreatic lymphoma presenting as pancreatitis include “ductal obstruction, ductal rupture with direct parenchymal tumor invasion, and ischemia secondary to vascular occlusion by tumor” (7). There are two described patterns of pancreatic Linifanib (ABT-869) involvement: (I) a discrete, well circumscribed tumor; and (II) a diffuse infiltrating process that may mimic findings of acute pancreatitis on imaging, such as seen in our case (8). Interestingly, a review in the American Journal of Radiology stated that the latter pattern “never show[s] the typical clinical signs of acute pancreatitis even if the serum amylase is elevated” (8), but this statement is contradicted by the findings of our case.

43 over other genotypes, and 10.67 over the most protective genotype.93 An association of the same leucine allele for NPAS2 471 had been reported previously.94 In addition, this study supported a relationship between the PER3 647 Val/Gly genotype and mornlngness /eveningness, particularly in the SAD group.94 This reinforces

the suggestion of an association between certain clock gene polymorphisms and chronotype. Also, it suggests that certain abnormalities in the circadian molecular clock increase the susceptibility to SAD. Schizophrenia #DAPT ic50 keyword# Sleep abnormalities have been consistently found in schizophrenia, although the results have not been consistent across studies.95 These include insomnia, Inhibitors,research,lifescience,medical reduced total sleep time (TST), increased sleep latency, poor sleep consolidation and sleep efficiency, and low levels of SWS, with insomnia frequently signaling relapse.96 Actigraphlc recordings of schizophrenic patients have revealed disturbed rest-activity cycles, showing either phase delays, longer periods of activity, or clrcabidlan rest-activity patterns.97-99 The study of schizophrenic patients by a forced desynchrony experiment revealed an abnormal circadian propensity for sleep suggesting a disturbed circadian regulation of sleep.100 Another study reported desynchronizatlon of Inhibitors,research,lifescience,medical CBT, pulse and blood pressure rhythms.101 The analysis of melatonin secretion demonstrated blunted

circadian variation.102-104 Others have reported phase advances of prolactin, melatonin and tryptophan.105 Evidence linking circadian clock gene polymorphisms or deregulation with schizophrenia is limited. In one study, SNP analysis of the CLOCK gene demonstrated that the T3111C polymorphism showed a transmission bias in a sample Inhibitors,research,lifescience,medical of Inhibitors,research,lifescience,medical 145 Japanese schizophrenic subjects relative to healthy controls.106 The authors suggested that this polymorphism, associated with aberrant dopaminergic transmission to the SCN may underlie the pathophysiology of schizophrenia. Since dopaminergic signaling through D2 receptors appears to be associated with increased CLOCK:BMALl activity,107 this provides an interesting link

Rolziracetam between the dopaminergic hypothesis of schizophrenia and circadian abnormalities in these patients. Post-mortem studies have shown decreased expression of the PERI mRNA in the temporal lobe of schizophrenic subjects compared with age-matched normal controls.108 Associations of PER3 and TIMELESS have also been found with schizophrenla/schizoaffectlve disorder, as well as with bipolar disorder.77 The association with PER3 is interesting, given the evidence of a relationship between PER3 with DSPD and evening chronotype. However, the function of TIMELESS in mammals is not yet clear,109 making it difficult to interpret this finding. Finally, the CRY1 gene was hypothesized to be a candidate gene for schizophrenia based on its location near a linkage hotspot for schizophrenia on chromosome 12q24.

The right hemisphere, by contrast, is actively watching for discrepancies, more like a devil’s advocate.140 Both approaches are needed, but are mutually contradictory. These differences operate across all realms and apply equally to the verbal as to the visuospatial. For example, the left hemisphere operates focally, suppressing verbal meanings that are not currently relevant, whereas the right Inhibitors,research,lifescience,medical hemisphere recruits

wider semantic associations,141-145 and the right posterior superior temporal sulcus may be selectively involved in verbal creativity146 In the “close” situation, by contrast, the left hemisphere actively suppresses the right, to exclude associations which are semantically only distantly related.147,148 Integration versus division In general the left hemisphere is more closely interconnected within itself, and within regions of itself, than the right hemisphere.14,17 By contrast, the right hemisphere Inhibitors,research,lifescience,medical has a greater degree of myelination, facilitating swift transfer of FDA-approved Drug Library information between the cortex and centers below the cortex,17 and greater connectivity in general.149 Functionally, its superior integration is evidenced by EEG measures150 and by

the more diffuse but overlapping somatosensory Inhibitors,research,lifescience,medical projections and auditory inputs in the right hemisphere.151 At the experiential level it is also better able to integrate perceptual processes, particularly bringing together different kinds of information from different senses.109,154,155 By contrast, the left hemisphere may be ‘inadequate for

Inhibitors,research,lifescience,medical the more rapid complex syntheses achieved by the [right] hemisphere.’156 As mentioned, new stimuli lead to release of noradrenalin in the right hemisphere. Its neurons are relatively resistant to fatigue, so that exploratory attention is held Inhibitors,research,lifescience,medical open across a greater expanse of both space and time.21 The range of the right hemisphere is further increased by the fact that it has a longer working memory, and so is able both to access more information and hold it together at any one time for longer.157 It is capable of bearing more information in mind and doing so over longer periods, with greater specificity (which also means less susceptibility to degradation over time by memory).128,157-159 This broader field of attention, open to whatever may be, and coupled with greater integration over time and space, Resminostat is what makes possible the recognition of broad or complex patterns, the perception of the “thing as a whole,” seeing the wood for the trees.160-163 In short, the left hemisphere takes a local short-term view, where the right hemisphere sees the bigger picture. The whole versus the part The link between the right hemisphere and holistic or Gestalt perception is one of the most reliable and durable of the generalizations about hemisphere differences, which follows from the differences in the nature of attention.
