“The incidence of major amputation in diabetes varies up to 10-fold between primary care trusts (PCTs) in England. Historically, there have

been concerns about the reliability of databases which are used to obtain such figures, but the available evidence suggests that the documented variation is likely to be real. While a high prevalence of ethnic minorities may contribute to the low incidence observed in some PCTs, it is also thought the variation may relate largely to the structure of available specialist services. This paper reviews the factors which need to be considered in exploring possible explanations for the variation which has been observed. Copyright © 2012 John Wiley & Sons. “
“The electronic age is bringing advances in the treatment of diabetes, and this is important because the

complications of diabetes remain Selleckchem GSK-3 inhibitor click here despite the availability of effective therapeutic tools such as insulin. These developments focus on the need to deliver accurately timed and sized doses for predicted blood glucose levels. In this review, blood monitoring methods are discussed since, although the chemistry remains based on the enzymic oxidation of glucose, the display, storage and manipulation of data have transformed recently to engage with smartphone users. Continuous glucose monitoring sensing (CGMS) types are described along with an appreciation of the shortcomings of sensor technology. The discussion includes responses to other barriers to CGMS use for reducing the HbA1c value safely so that hypoglycaemia can be avoided. The newer pumps and the emergence of the minimalised patch pumps and patch pens are described. This includes the moves to attract more type 2 users to pump use, addresses the perceived obtrusiveness noted by younger users, and reviews the obstacles to rolling out pump use more widely in the UK. Penultimately, after reference to

islet implants, the combination of the continuous sensing and conventional pump strategies to form a closed Pregnenolone loop system is described, including a summary of the electronic algorithms and the clinical performance of systems in research settings. The review closes with an explanation of how other closed loop systems have been developed including the peritoneal Medtronic and the DiaPort and a smart gel, non-electronic design.

“Type 2 diabetes is common and is associated with progressive beta cell loss, insulin deficiency, organ damage and effects on mental health and wellbeing. The current management focus is on stringent blood glucose control (HbA1c <7% [53mmol/mol]) and early insulin initiation. Insulin is a high-risk medicine and is associated with a high rate of errors, adverse events and admissions to hospital.

The clinical manifestations of NCC depend on both the location of

The clinical manifestations of NCC depend on both the location of the cyst and the size and number of cysts. The most common symptom is epileptic seizures, but headache with increased intracranial pressure, hydrocephalus, motor deficits, meningitis, HM781-36B research buy and psychiatric symptoms have all been reported.7 NCC is increasingly diagnosed in developed countries among immigrants from endemic areas.4 However, data about NCC in travelers is scarce and mainly consists of case reports. There are no estimates of the burden of the disease among travelers. This report summarizes a nation-wide study of NCC diagnosed among Israeli travelers to endemic countries, with an estimation of disease incidence among the traveler

population. We performed a retrospective, nation-wide

survey of travel-related NCC in Israel between the years 1994 and 2009. All major hospitals in Israel were contacted. All cases of NCC (DSM code no. 123.1) during the study years were identified and Navitoclax patient files were reviewed. The following diagnostic criteria were used to define cases of NCC: clinical manifestations of CNS involvement (seizures, headache, and/or focal neurologic deficit) combined with radiological findings suggestive of NCC. In some cases, serology and/or brain biopsy histologo-pathological results were available. Travel-related NCC cases were identified by an epidemiological background compatible with travel to endemic countries. Immigrants and Israeli citizens without travel Sclareol to endemic countries were excluded. Serological tests, when available, were performed by the Centers for Disease Control and Prevention (CDC), Atlanta, GA, USA laboratories using the CDC’s enzyme immuno-transfer blot assay with purified T. solium antigens. This assay is extensively described elsewhere.8 Epidemiologic data regarding the Israeli traveler population were available from an Israeli survey.9 This study was approved by the Sheba Medical Center internal review board. During the years 1994 to 2009, 17 cases of NCC were diagnosed in different

Israeli hospitals. Among them, nine cases were found among Israeli travelers to endemic areas, whereas the rest were among immigrants or locally acquired.10 Only the nine travelers are included in this study (Table 1). Previous travel to South and Southeast Asia (including the Indian subcontinent) was documented in seven of nine patients (78%), prior travel to South America was documented in one patient, and another had multiple trips to India, South America, and Central America during the years before diagnosis. Eight patients were males (89%). The average interval (± SD) between return from the suspected travel and symptom onset was 3.2 ± 1.8 years (this was determined in five patients, in three patients data were unavailable, and in one there were multiple trips). The average age was 28 ± 6 years old (range 24–45 years old). The most common symptom at diagnosis was a seizure.

Furthermore, production of mitochondrial superoxide radicals incr

Furthermore, production of mitochondrial superoxide radicals increased significantly when cells were irradiated with 411 nm light at 4.5 W/m2. In addition, such irradiation caused an activation of the antioxidative glutathion system. this website Using vital staining, flow cytometry and western blotting, we were able to show that

apoptosis only took place when cells were exposed to 411 nm blue light at higher irradiances; necrosis was not observed. Enhanced caspase-3 cleavage product levels confirmed that this effect was dependent on light irradiance. Significant alterations of the above-mentioned parameters were not observed when cells were irradiated with 471 nm light despite a high irradiance of 4.5 W/m2, indicating that the cytotoxic effect of blue light is highly dependent on wavelength.

The observed phenomena in R28 cells at 411 nm (4.5 W/m2) point to an apoptosis pathway elicited by direct mitochondrial damage and increased oxidative stress. Thus, light of 411 nm should act via impairment of mitochondrial function by compromising the metabolic situation of these retinal neuronal cells. “
“There is a strong interest in harnessing the genetic manipulations that are possible in mice to investigate the functional neural mechanisms modulating the associative processes that control drug-seeking behavior. However, it is unknown whether intracranial techniques, such as the disconnection procedure commonly used in rats to examine serial connectivity between implicated areas, can be successfully applied selleck chemicals llc to mice. We have previously demonstrated that the expression of ethanol-seeking behavior in mice is dependent upon amygdala Silibinin (Amy) dopamine and nucleus accumbens (Acb) N-methyl-d-aspartate (NMDA) receptor activation (Gremel & Cunningham, 2009). Here, we used a neuropharmacological disconnection procedure to investigate whether dopamine activation of the Amy directly leading to increases in Acb glutamate release and binding of NMDA receptors modulates the expression

of ethanol-seeking behavior. Immediately before testing the expression of an ethanol-induced conditioned place preference, mice were given an Amy infusion of flupenthixol and either an ipsilateral or contralateral Acb infusion of AP-5. Although both ipsilateral and contralateral manipulations reduced the expression of ethanol conditioned place preference, in a separate experiment we demonstrated that a unilateral Acb infusion of AP-5, but not Amy flupenthixol, is sufficient to disrupt preference. The finding of a significant blockade by unilateral AP-5 into the Acb precludes any conclusions about a unique role for the Amy/Acb neuroanatomical connection in this model of ethanol-seeking behavior.

However, none of the genomes from strains that originated from animals have

been studied. A group of bacterial strains previously known as CDC group M-5 are part of the normal canine oral flora, but it has known opportunistic pathogenicity in human peritonitis (Kocyigit et al., 2010), lower respiratory tract infections (Panagea et al., 2002), cervical and vaginal infections (Flores-Paz et al., 2003), wound infections (Capitini et al., 2002), and septicemia (Carlson et al., 1997). In 1993, a name, Neisseria weaveri, has been proposed by two independent studies to harbor CDC group M-5 strains, namely N. weaveri Holmes et al. 1993 and Pifithrin-�� mouse N. weaveri Andersen et al. 1993 (Andersen et al., 1993a, b). The type strain defined by Holmes et al. (1993) was isolated from human dog bite wound in Göteborg, Sweden (1974) and that defined by Andersen et al. (1993a) was isolated from same type of wound in New York, USA (1962). Even though both taxa were published in the same volume of International Journal of Systematic Bacteriology (IJSB), N. weaveri Holmes et al. 1993 has page

precedence over N. weaveri Andersen et al. 1993 according to Bacteriological Code Rules 51b (4) and 24b (2) (Lagage et al., 1992). Thus, N. weaveri Andersen et al. 1993 is illegitimate because it is a later homonym of N. weaveri Holmes et al. 1993 (Euzéby, 1998). Although different type strains were deposited as representing N. weaveri, the close relationship of the two taxa has long been accepted because of the similar pathogenic characteristics of the two ‘type’ strains. However, there has been no systematic

investigation about the relatedness of these two ‘type’ strains and thus the illegitimate name has remained as a homonym and not transferred as a synonym of N. weaveri Holmes et al. 1993. Thus, in this study, we attempt to resolve the confusion caused by two N. weaveri species with different ‘type’ strains ADP ribosylation factor using whole genome shotgun sequencing. We also sought to gain insight into the genetic characteristics of N. weaveri by conducting comparative genomics. The ‘type’ strains of N. weaveri Holmes et al. 1993 (LMG 5135T) and N. weaveri Andersen et al. 1993 (ATCC 51223T) were obtained from LMG and ATCC, respectively, and the genomic DNAs were extracted using DNeasy Blood & Tissue kit (Qiagen). The draft genome sequences of strains LMG 5135T and ATCC 51223T were determined by paired-end shotgun sequencing using the Genome Analyzer IIx (Illumina) with > 1000× fold coverage. The sequencing reads were assembled using the CLC genomics wb4 (CLCbio) and CodonCode Aligner (CodonCode Co.).

, 2008). Because cloxacillin is an inhibitor

of AmpC-like enzymes, and amoxicillin and clavulanic acid are inducers of inducible AmpCs (Livermore, 1995), this test may also provide information about the AmpC expression and its mode (Drieux et al., 2008). Crude bacterial extracts were subjected to isoelectric focusing (IEF) and to a bioassay for the detection of enzymes with cefotaxime- or ceftazidime-hydrolyzing activity (Fiett et al., 2000). Plasmid DNA, purified using a NucleoBond® Xtra Midi kit (Machery-Nagel, Duren, Germany), was used for PCR and sequencing of blaSHV genes (Fiett et al., 2000). The multiplex PCR for acquired ampC-type genes was performed as described by Pérez-Pérez & Hanson (2002), followed by PCR and sequencing Selleck CYC202 of entire blaDHA genes (Verdet et al., 2006). Typing by the

pulsed-field gel electrophoresis (PFGE) was performed as described previously (Fiett et al., 2000) using the XbaI restriction enzyme (Fermentas, Vilnius, Lithuania); banding patterns were interpreted according to Tenover et al. (1995). PFGE subtypes were distinguished when differences of 1–3 bands were observed between the patterns. All of the isolates were subjected to multilocus sequence typing (MLST) as described by Diancourt et al. (2005). The database available at was used for assigning sequence types (STs). The genetic context of the blaDHA-1 gene Navitoclax price was analyzed by PCR mapping (Verdet et al., 2006), followed by separate amplification and sequencing of integronic gene cassettes. Major outer membrane proteins were purified using the rapid procedure with sodium N-lauryl sarkosinate and electrophoresed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE; 12.5% separating gels) (Kaczmarek et al., 2006). The analysis was completed by a Western blot with polyclonal antibodies against OmpK35 and OmpK36 major porins (Doménech-Sánchez et al., 2003). The PCR amplification of ompK35 and ompK36 genes was carried out according to Kaczmarek et al. (2006). The ompK36 gene was also analyzed with

alternative primers, OmpK36-F (5′-GTCCCTCCTGGTACCGGCTC-3′) and OmpK36-R (5′-TGCCAGACGAGTCCATGCCT-3′). PCR products corresponding to the two omp genes were sequenced. The expression of ompK35 and ompK36 genes was analyzed by RT-PCR. Total mRNA was purified using the Aurum Total RNA 96 kit with a DNA hydrolysis step (Bio-Rad, Prague, Czech Republic). The AgPath-ID™ One-Step RT-PCR kit (Applied Biosystems, Prague, Czech Republic) was used for RT-PCR according to the manufacturer’s recommendations. The analysis was performed with the primers: OmpK35-F (5′-GTGGTGATCCCTGCCCTGCT-3′) and OmpK35-R (5′-CCACTGGCCGTAGCCGATCA-3′), and OmpK36-F and OmpK36-R, and with TaqMan probes: OmpK35 [5′-(FAM)-TCGGCGAGCACGTCTGGACCACCAAT-(BHQ)-3′] and OmpK36 [5′-(FAM)-CGTCGACGGCGACCAGACCTACAT-(BHQ)-3′], respectively.

, 2010). It was hypothesized that a group of highly hydrophobic GS-1101 datasheet conidia might include colonies with enhanced thermotolerance. Mycotized agar discs were collected from the cultures, placed in 0.2% siloxane solutions, and adjusted to 1 × 107 conidia mL−1 as described

above. The conidial suspensions were diluted twofold (finally 5 × 106 conidia mL−1) using 0.08% siloxane to avoid their spreading over onto the surface of the ¼SDAY medium due to the higher surface tension activity of the 0.2% siloxane solution. All suspensions (50 μL per plate) were spread on the medium and incubated for 10 days under the same conditions. The same methods were applied to the next cycling. After the third cycling, colonies were isolated from the paired culture through a heat treatment at 45 °C for 90 min as a selection pressure (Kim et al., 2011). Colonies from

the third cycled non-paired cultures, EX 527 chemical structure which were exposed to the same heat treatment, served as controls. The heat treatment was used to collect colonies with highly enhanced thermotolerance. If the frequency of hyphal fusion is low, this heat exposure can be used to efficiently isolate thermotolerant colonies. If no heat treatment is used, low populations of colonies with enhanced thermotolerance may not be isolated using the streaking method, which mainly isolates predominant colonies. In each culture, a mycotized agar disc (6 mm diameter) was collected from a Petri dish, placed in 0.2% siloxane Erastin nmr solution, and vortexed for 30 s. The conidial suspension was adjusted

to 1 × 107 conidia mL−1 as described above. All suspensions were diluted twofold using 0.08% siloxane to avoid spreading over onto the media. They were transferred to Eppendorf tubes (200 μL per tube), and the tubes were placed in a water bath at 45 °C for 90 min for a heat treatment. The heating time was set based on a previous report that the viability of B. bassiana conidia was very susceptible to this condition (90 min exposure; < 10% conidial population viable) (Kim et al., 2011). Conidial suspensions were individually streaked on ¼SDAY and incubated at 25 °C for 7 days. The colonies that survived were photographed and then observed/tested to determine whether the colonies from the paired culture were different from each of the non-paired colonies relevant to morphology, thermotolerance and virulence against WFT. For this, mycotized agar discs (6 mm diameter) from the surviving colonies were placed individually in 0.2% siloxane solutions and conidial suspensions were prepared for propagation as described above (dilution: twofold using 0.8% siloxane). Following incubation at 25 °C for 10, 14 and 20 days, the number of conidia per unit area of agar disc was determined by counting conidia from the disc using a hemacytometer after making a conidial suspension.

7 After reviewing comparable published estimates on global typhoi

7 After reviewing comparable published estimates on global typhoid incidence, the authors developed incidence brackets for each destination, dividing them into three categories: low if <10/100,000 cases/year; medium if 10–100/100,000 cases/year; and high see more if >100/100,000 cases/year. Because country-level incidence data do not always adequately represent a traveler’s risk for acquiring typhoid fever, incidence classifications were compared to CDC’s national surveillance

database of travel- and domestically acquired typhoid fever cases in the United States.8 All travel-related cases reported to CDC during 1999–2008 were matched to their reported countries of exposure to determine where travelers are most often exposed to typhoid fever. A total of 2,077 records were reviewed. Countries were ranked by the cumulative number of imported cases during this timeframe as a proportion of all cases reported to CDC. This step was included PD0332991 price to identify any “hotspots” for typhoid exposure among US travelers that may not be reflected in endemic incidence rates. It was not possible to calculate incidence rates because we could not accurately determine the number of US travelers exposed. Therefore, we did not set numeric cut-offs for

low, medium, filipin and high rates of imported cases. On a case-by-case basis, the review team compared the endemic incidence rate to the proportion of imported cases among US travelers to assign a destination-specific risk category for each country. These destination-specific risk categories were then used to inform destination-specific recommendations for pre-travel typhoid vaccination. Based on consensus among CDC experts in THB and enteric diseases, it was decided that vaccination would be recommended

for destinations falling into the medium- and high-risk categories, while the low-risk category would result in a recommendation not to vaccinate. As a result of this review, the typhoid vaccine recommendation remained unchanged for 212 (89%) of the 238 destinations. Changes did occur in the Eastern European and Middle Eastern regions, where 26 countries for which typhoid vaccine was previously recommended based on presumed risk, were downgraded to the low-risk category (Figure 1). These destinations are Albania, Armenia, Azerbaijan, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Estonia, Georgia, Hungary, Israel, Kosovo, Latvia, Lithuania, Macedonia, Moldova, Montenegro, Poland, Romania, Russia, Serbia, Slovakia, Slovenia, and Ukraine.

These findings suggest that AoAtg1 plays an essential role in the

These findings suggest that AoAtg1 plays an essential role in these pathways in A. oryzae. Based on the observed localization of EGFP–AoAtg8 in the ΔAoatg1 disruptant, EGFP buy Dinaciclib fluorescence was not detected in vacuoles even under starvation conditions, whereas EGFP puncta were formed under both nutrient-rich

and starvation conditions. It appears that the punctate structures observed in the strain expressing EGFP–AoAtg8 differed from the PAS-like structures observed in WT. Although PAS is generally localized to the periphery of vacuoles in WT, the punctate structures in ΔA1EGA8 were observed not only around vacuoles but were also found in the cytoplasm and, in addition, were larger in size than the PAS of WT. This result is consistent with the finding in S. cerevisiae that PAS-like punctate structures in an atg1 mutant are larger than those of WT and that an overabundance of Atg proteins is assembled to PAS, suggesting that Atg1 functions in the formation of autophagosomes from PAS (Suzuki et al., 2001). In a temperature-sensitive atg1 mutant (apg1ts), punctate structures of GFP–Atg8, which are excessively assembled at restrictive temperatures, are transported to vacuoles after a shift to permissive temperature (Suzuki et al., 2001). This phenomenon suggests that the punctate structures observed in

Aoatg1 disruptants are an assembly Torin 1 order of AoAtg proteins that results due to inhibition of autophagosome

formation from PAS. Our localization analysis of the EGFP-fused prApe1 homolog in A. oryzae represents the first such analysis in a filamentous fungus. After incubation of the WT and ΔA1Ape1EG strains for 20 h at 30 °C, we observed AoApe1–EGFP fluorescence in vacuoles of in WT, whereas that in ΔA1Ape1EG was not detected in vacuoles, but appeared as punctate structures in the cytoplasm. The localization pattern did not change even when ΔA1Ape1EG was shifted to starvation conditions. These results suggest that A. oryzae has a functional Cvt pathway and that the punctate structures observed in ΔAoatg1 were not Cvt vesicles, but rather were clusters of AoApe1 proteins. Genome-wide functional analysis in M. oryzae revealed that nonselective autophagy was an important factor of plant infection, and clear orthologues of S. cerevisiae genes required for the Cvt pathway, such as ATG19, were not found in the M. oryzae genome sequence (Kershaw & Talbot, 2009). Therefore, the Cvt pathway is considered to be missing in M. oryzae. Also, the Cvt pathway -specific proteins in S. cerevisiae are poorly conserved in A. oryzae, suggesting the existence of a functional homolog that is unable to be identified by homology searches. Atg13 plays an essential role in autophagy, as demonstrated by the disruption of atg13 in yeast, which results in the impaired ability to form Atg1 kinase complexes to induce autophagy (Kabeya et al., 2005).

Enrichments of n-damo bacteria, members of NC10 phylum, were star

Enrichments of n-damo bacteria, members of NC10 phylum, were started from freshwater sediments (Raghoebarsing et al., 2006; Ettwig et al., 2009) and wastewater treatment sludge (Luesken et al., 2011a,c). In 2010, the genome of Methylomirabilis oxyfera, the bacterium responsible for n-damo, was assembled and analyzed (Ettwig et al., 2010). The remarkable presence of genes encoding for particulate methane monooxygenase (pmoCAB) in this anaerobe was explained by its unusual intra aerobic metabolism. Recently published primers specifically targeting the pmoA subunit of n-damo bacteria were used to screen environmental samples, and n-damo bacteria were detected in a wide range of freshwater habitats (Deutzmann & Schink,

2011; Luesken et al., 2011b; Kojima et al., 2012). Paddy fields are characteristized by cultivation patterns Silmitasertib in vivo including water logging, which causes anoxic soil conditions. Plant-derived organic substances additionally serve as an important carbon source for CH4 (Lu & Conrad, 2005). In addition, application of nitrogen-rich fertilizers makes the paddy field a favorable habitat for both anammox and n-damo bacteria. In the present study, we aimed to explore the co-occurrence and vertical distributions of

anammox and n-damo bacteria in a paddy soil core with our newly developed anammox primers targeting the β subunit of the hydrazine synthase (hzsB gene) and the primers targeting the pmoA and 16S rRNA genes of n-damo bacteria. Both quantitative and biodiversity analyses are reported. A paddy field with long-term manure fertilization practice in subtropical China (E120°41′50″ N30°45′50″) was selected for this study. Five soil cores Bay 11-7085 (1 m distance) were collected by a stainless steel ring sampler (5 cm diameter and 100 cm depth) from the field in October 2009 at the growth season. The soil cores were placed in sterile plastic bags, sealed, and transported to the laboratory on ice. Later they were sliced at 10-cm intervals, and slices of the same depth were mixed to form one composite sample. One part was sieved through 2.0-mm sieve for the chemical analysis, and subsamples were used for DNA extraction. To evaluate the

designed primers, biomass from several anammox enrichment cultures in bioreactors from our laboratory (Nijmegen, The Netherlands) were sampled including ‘Candidatus Kuenenia stuttgartiensis’, ‘Candidatus Brocadia fulgida’, ‘Candidatus Brocadia anammoxidans’, ‘Candidatus Scalindua sp.’, and ‘Candidatus Jettenia asiatica’. The cultures were each dominated at 70–95% by single anammox species. The enrichment and cultivation profiles see the previous works (Kartal et al., 2007; Quan et al., 2008; Schmid et al., 2008). Environmental samples from wastewater treatment plants (WWTPs) and sediment were investigated from the Rotterdam and Lichtenvoorde full-scale anammox reactors (Van der Star et al., 2007) and ditches in the Ooijpolder, Olburgen, and Propionaat (The Netherlands), respectively (Hu et al.

Motor imagery of catching the ball, as compared with baseline, le

Motor imagery of catching the ball, as compared with baseline, led to an increase in BOLD activity in cortical sensorimotor areas of the left

hemisphere and the right posterior cerebellum (Table 1). The cortical areas involved were the left supplementary motor area (SMA; Fig. 3A), the left IFG (Fig. 3B), the left posterior insula, the left postcentral gyrus, and the left IPL (Fig. 3B). In addition, the left anterior superior prefrontal cortex, the ventral ACC and the right inferior temporal cortex were activated (Table 1). To explore the BOLD changes found in the motor imagery condition in comparison with the action and observation conditions, regional analyses were performed across the following regions of interest: left ACC, left IFG, left SMA, and left IPL. We found a significantly higher degree of activation in the left SMA during EPZ-6438 datasheet motor imagery than during active catching [T = −3.44, degrees of freedom (df) = 16, P = 0.003, Cohen's d = 0.8] and observation of catching [T = 3.57, df = 15, P = 0.003 (Fig. 4); pairwise t-tests with Bonferroni correction α = 0.003

and additional effect size Cohen's d]. The same pattern was observed for the left IFG (motor imagery vs. catching, T = −2.51, df = 16, P = 0.023, Cohen’s d = 0.6; motor imagery vs. observation, T = 2.26, df = 15, P = 0.039; Fig. 4) and left IPL AZD2014 cell line (motor imagery vs. catching, T = −1.93, df = 16, P = 0.071, Cohen’s d = 0.5; motor imagery vs. observation, T = 1.84, df = 15, P = 0.086; Silibinin Fig. 4), although the medium effect as indicated by Cohen’s d was not statistically significant. Note that, in the left IFG and left IPL, there was no change in BOLD activity in the catching trial. No differences in the degree of activation were found when active catching and the observation of catching were compared within all regions of interest defined. In the current

fMRI study, as a first step to explore the neural correlates of RGS, we investigated in healthy volunteers whether actual or imagined catching of moving balls modulated the activity in candidate areas of the human mirror neuron system in frontal and parietal cortical areas. In order to address this question, we adapted the RGS to the fMRI environment, and compared active, passive and imaginary task conditions within a VR world. Similarly to the clinically used RGS, the MRI-adapted version simulated natural activities while maintaining action control by pressing of buttons to steer the avatar. In agreement with the working hypothesis behind the RGS, we observed the activation of a number of brain areas in the imagination condition, including the left SMA, the left IFG, the left posterior insula, the left postcentral gyrus, the left IPL, and the right cerebellum. These areas constitute a widespread circuit of sensorimotor areas including key cortical areas of the human mirror neuron system (Gallese et al., 1996; Iacoboni & Mazziotta, 2007; Sale & Franceschini, 2012).
