| Outline of Final Research Achievements |
To investigate salience detection mechanisms in primates, we analyzed neuronal responses to visual stimuli in the extrageniculate system (superior colliculus, and pulvinar) as well as the medial frontal cortex that receives anatomical projections from the extrageniculate system in monkeys. The results indicated: 1) the medial frontal cortical neurons receive fast and coarse inputs from the extrageniculate system, and are involved in the detection of stimuli with biological salience (snakes and conspecific faces), and 2) collicular neurons in the deep layers showed climbing activities during the delay intervals before appearance of rewarding stimuli, and are involved in the temporal salience detection mechanisms predicting the emergence of rewarding stimuli.
