Research Abstract

To study cerebral mechanisms in the perception and retrieval of color and face ofprimates, we recorded electrocorticographic (ECoG) activities in the inferotemporal and prefrontal cortices of monkey that were performing tasks requiring perception or retrieval of such visual contents. We found that stimulus-specific patterns of ECoG activities in these cortices during perception and retrieval. We were also able to decode visual contents of perception and retrieval only from ECoG activities using a machinelearning technique.
