• The last 10 years, however, have seen increased recognition within the fMRI community that information can also be encoded in the activity patterns of populations of voxels. (frontiersin.org)
  • The effects of a single dose of the alkylating agent cyclophosphamide (CPA or 4-hydroperoxycyclophosphamide), or the mechanism-based small molecule SMAC mimetic birinapant on caspase-3 activation was assessed in vitro and by [ 18 F]ICMT-11-PET in mice bearing 38C13 B-cell lymphoma, HCT116 colon carcinoma, or MDA-MB-231 breast adenocarcinoma tumors. (aacrjournals.org)
  • Moreover, we demonstrate decreased activation in the rostral basal ganglia and midbrain, key structures of the reward system, following unexpected high gains and therefore propose that pathological gambling in PD results from the need to seek higher rewards to overcome the blunted response in this system. (plos.org)
  • BACKGROUND: Previous studies indicate that youth with posttraumatic stress disorder (PTSD) have abnormal activation in brain regions important for emotion processing. (stanford.edu)
  • Meta-regression analyses showed that studies that included individuals with more severe OCD were significantly more likely to report increased grey matter volumes in the basal ganglia. (cambridge.org)
  • 2010) reported brain activation during a social cognition task in a dead salmon as an illustration of the inadequacy of commonly used corrections for multiple comparisons 8 , and a recent publication by Eklund et al . (nature.com)
  • Subjective liking per se caused differential activation in the left hemisphere, of the anterior insula, the caudate nucleus, and the putamen. (hindawi.com)
  • We hypothesized that the right lateral prefrontal cortex would play a role in the MEE for music, as it did for visual stimuli [ 9 ], that is, show differential activation as a function of prior exposure. (hindawi.com)
  • A new improved voxel-based meta-analytic method, signed differential mapping (SDM), was developed to examine regions of increased and decreased grey matter volume in the OCD group v. control group. (cambridge.org)
  • The acquired clusters were further included as a factor in survival analyses. (ajnr.org)
  • Statistical analysis demonstrated that the left medial temporal lobe and right anterior temporal lobe were specifically associated with high expression of mutant p53. (ajnr.org)
  • Task activation secondary to text listening, finger tapping, and word generation was mapped by use of fMR imaging. (ajnr.org)
  • In each case, we compared one fcMR map with a task-activation map in the same subject. (ajnr.org)
  • Using a voxel-based lesion-symptom mapping analysis, we located brain regions associated with a high occurrence of p53 mutation and corrected them by using a permutation test. (ajnr.org)
  • Activation of the ventral striatum following wins was found to be decreased compared to healthy control subjects and correlated negatively with gambling severity . (plos.org)
  • fMRI and PET offer relatively high spatial resolution, with voxel dimensions on the order of a few millimeters, but their relatively low sampling rate hinders the observation of rapid and transient interactions between distant regions of the brain. (wikipedia.org)
  • The areas with significant likelihood of activation in one or multiple tool-relevant tasks are sorted by Brodmann's labelling (BA = Brodmann area) and classified to the corresponding territory in the diagram. (nih.gov)
  • Furthermore, activation in a distributed brain network known to underlie the aesthetic evaluation of different types of visual stimuli covaried with beauty ratings. (pnas.org)
  • Multivariable analyses show that dementia and cognitive impairment are by far the most strongly and independently associated chronic health disorders [ 3 ]. (hindawi.com)
  • These include psychophysiological interactions in general linear models, structural equation modeling, dynamic causal modeling, and independent components analysis. (frontiersin.org)
  • The Alicia Koplowitz Foundation played no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. (plos.org)
  • B) Summary of individual and conjunction ALE analyses in the form of a Venn diagram. (nih.gov)
  • The sponsors had no role in the design, execution, analysis or interpretation of the reported research. (plos.org)
  • And it becomes it's own viable level of analysis, for predicting performance. (coursera.org)
  • Our voxel-level imaging analysis provides new evidence that genetic changes during cancer may have anatomic specificity. (ajnr.org)
