Fig. 6. Electrodes on the posterior fusiform gyrus encode stimulus persistent presence and its category.

Four significantly duration-tracking electrodes in three subjects were found within category-selective IT cortex, all located adjacently to the mid-fusiform sulcus on the posterior fusiform gyrus, as opposed to more anterior category-selective sites which do not track ongoing stimulus presence. Of these, the two face-selective electrodes (from two subjects) marked by arrows also maintained category-selectivity persistently throughout the duration of the response (marked with arrows) whereas the two others did not. The electrodes are presented on the subjects’ native brains.
