Overlapping but distinct: distal connectivity dissociates hand and tool processing networks

摘要: Abstract The processes and organizational principles of information involved in object recognition have been a subject intense debate. These research efforts led to the understanding that local computations feedforward/feedback connections are essential our representations their organization. Recent data, however, has demonstrated distal also play role how is locally processed. Here we focus on long-range connectivity functional organization related, by exploring regions show overlapping category-preferences for two categories testing whether related with category-specific way. We used an approach relates areas voxel-wise category-preferences. Specifically, focused overlap tools hands – inferior parietal lobule/anterior intraparietal sulcus (IPL/aIPS) posterior middle temporal gyrus/lateral occipital cortex (pMTG/LOTC) from these relate ventral dedicated processing separately left medial fusiform gyrus body area respectively as well across brain. correlate categorical preferences each category independently. results process both maintain topography This potentially allows flow pertinent computing representations.
