Distributed representation of objects in the human ventral visual pathway

摘要: Brain imaging and electrophysiological recording studies in humans have reported discrete cortical regions posterior ventral temporal cortex that respond preferentially to faces, buildings, letters. These findings suggest a category-specific anatomically segregated modular organization of the object vision pathway. Here we present data from functional MRI study which found three distinct responded faces two categories other objects, namely houses chairs, had highly consistent topological arrangement. Although could be interpreted as evidence for separate modules, each category also evoked significant responses maximally stimuli. Moreover, was associated with its own differential pattern response across cortex. results indicate representation an is not restricted region responds object, but rather distributed broader expanse We propose architecture visual pathway mosaic modules instead continuous information about form has orderly
