Population for the development of interventions and education to cut down restraint use.
Broad domain generality in focal regions of frontal and parietal cortexEvelina Fedorenkoa,b,, John Duncanc,d,, and Nancy Kanwishera,b,a Brain and Cognitive Sciences Division, Massachusetts Institute of Technology, Cambridge, MA ; bMcGovern Institute for Brain Analysis, Massachusetts Institute of Technologies, Cambridge, MA ; cCognition and Brain Sciences Unit, Healthcare Study Council, AMG9810 chemical information Cambridge CB EF, Uk; and dDepartment of Experimental Psychology, University of Oxford, Oxford OX UD, United KingdomContributed by Nancy Kanwisher, August , (sent for assessment July ,)Unlike brain regions that respond selectively to precise types of data content material, a variety of frontal and parietal regions are believed to become domain- and process-general: that is, active for the duration of a wide range of demanding cognitive tasks. Nonetheless, most previous proof for this functional generality in humans comes from methods that overestimate activation overlap across tasks. Here we present functional MRI proof from PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/23948114?dopt=Abstract single-subject analyses for broad functional generality of a particular set of brain regions: precisely the same sets of voxels are engaged across tasks ranging from arithmetic to storing details in operating memory, to inhibiting irrelevant information and facts. These regions possess a distinct topography, typically lying straight adjacent to domain-specific regions. As a result, additionally to domain-specific brain regions tailored to resolve particular issues of UNC-926 site longstanding importance to our species, the human brain also consists of a set of functionally common regions that plausibly endow us together with the cognitive flexibility necessary to solve novel difficulties.Multiple-demand program cognitive controlstriking feature of the human brain is that it includes cortical regions specialized for particular mental tasks, from perceiving visual motion, to recognizing faces, understanding language, and considering about others’ thoughts (e.grefs. and). Nonetheless, an equally striking feature of human cognition is our potential to resolve novel complications around the fly for which we cannot have ready-made, specialized brain machinery. We innovate on recipes when a crucial ingredient is missing, we feel by means of the feasible causes–and attainable solutions–when our automobile breaks down around the highway, and we invent white lies around the spot in awkward social conditions. How are we so cognitively versatile and revolutionary, and what brain regions endow us using the capacity to solve new problems that neither our eutionary history nor our person practical experience has specifically ready us for Primarily based on previous neuroimaging data, a plausible neural substrate for cognitive flexibility is offered by a precise set of frontal and parietal brain regions the activity of which will not appear to be closely tied to certain cognitive demands. Rather, activity in these regions increases for any wide selection of complicated behaviors (e.grefs. and). Comprising this network are regions around the dorsolateral surface with the frontal lobes (along the inferior frontal sulcusmiddle frontal gyrus), parts with the insular cortex, regions along the precentral gyrus, presupplementary and supplementary motor location (preSMA, SMA), components from the anteriormid cingulate, and regions in and around the intraparietal sulcus. We’ll refer to these regions because the multiple-demand or MD method, following DuncanAcross both human and nonhuman primate studies, these regions are typically li.Population for the development of interventions and education to reduce restraint use.
