Multi-dimensional scaling of face stimuli based on neuronal activities of monkey ventral and dorsal inferior temporal areas during face identification

Multi-dimensional scaling of face stimuli based on neuronal activities of monkey ventral and dorsal inferior temporal areas during face identification

Society for Neuroscience Abstracts 26(1-2): Abstract No -357 14

Neuronal activity was recorded from the dorsal (areas TEad and STPa) and ventral (area TEav and perirhinal cortex: PRh) part of the anterior inferior temporal cortex of monkeys during a delayed matching-to-sample task based on identification of faces (I-DMS task). In the I-DMS task, a sample stimulus was presented after fixation, then test ("match" or "non-match") stimuli were given following an inter-stimulus delay period. The visual stimuli were digitized images of faces of persons that were unfamiliar or familiar to the animal. The animal was required to identify the same person instructed in the sample; "Match" stimuli consisted of seven images of the person viewed from seven directions (-90degree, -45degree, -22.5degree, 0degree, 22.5degree, 45degree, 90degree). Some intervening ("non-match") stimuli were given until the "match" finally appeared. Neutral geometric patterns were also used as control. We performed a multi-dimensional scaling (MDS) of face stimuli based on neuronal responses to the stimuli. As the results show, faces in the same direction fell into relatively close positions in the MDS space for the areas TEad and STPa. While, familiar or unfamiliar faces were relatively clustered in the MDS space for the areas TEav and PRh. We also tested various time periods for MDS analysis and found that effects of familiarity on distribution of face stimuli in the MDS space for the areas TEav and PRh and those of face direction for the areas TEad and STPa were more clear in the late component than in the early component of neuronal responses. The results suggest different functional roles of the ventral (TEav and PRh) and dorsal (TEad and STPa) inferior temporal areas for face identification.
