The transverse occipital sulcus and intraparietal sulcus show neural selectivity to object-scene size relationships

摘要

a Small object (toothbrush), normal object-scene scale consistency level. b Small object (toothbrush), maximum mis-scaled level. c Large object (car), normal object-scene scale consistency level. d Large object (car), maximum mis-scaled level. Images a and b show a retinal size manipulation (fixed scene field-of-view (FOV), with changing object retinal size). Images c and d show a scene FOV manipulation (fixed object retinal size, with changing FOV). e Schematic of a single trial presentation in the fMRI experiment. For visibility here, the central fixation point is shown larger than the actual size used and with a lighter gray outer ring (in the actual experiment the gray ring matched the background gray of the screen). f Example of the event order in a single scan. Each vertical multi-colored line indicates the onset time of an event, with the property levels for each of four properties that can be defined in the images (scale consistency, object retinal size, real-world size, scene field-of-view) indicated by color (see legend).
