Research Abstract

The aim of this study is to elucidate the neural mechanism of visual awareness using animal model of blindsight. We recorded the neural activities of the superior colliculus of the monkeys and found that their visual response is stronger when the monkeys were able to detect visual stimuli that when they failed to it. We found that such activity was developed during the transmission of visual information through the superficial layer of the superior colliculus to the intermediate later of the superior colliculus. These findings suggest that neural correlate of visual awareness develops within the local circuit of the superior colliculus.
