Activity of Neurons in Inferior Temporal Cortex Correlates with Monkey's Seen-not seen Choice Variation in a Stimulus Detection Task

Abstract (in Japanese) (See Japanese page) 
(in English) Many studies used a 2-alteranative forced choice task to investigate the correlation between monkey’s perceptual decision and neural activity near psychophysical threshold. However, since subjects may be able to perform better than chance level without any subjective percept (known as Unconscious Perception) in near-threshold condition, detection tasks are more preferable to investigate neural correlates of subjective percept. We recorded neuronal activities from inferior temporal (IT) cortex of a monkey performing a shape detection task. Evaluating correlation between monkey’s seen vs. not-seen choice variation and neuronal activity variation using Choice Probability index of signal detection theory, we found that variation of neuronal activities in IT and monkey’s detection were significantly correlated. This result suggests that IT neuronal activities are linked to visual awareness of a stimulus.
