| Outline of Final Research Achievements |
We investigated the responses in the higher visual cortex of conscious mice. The posterior-ventral cortical areas adjacent to the auditory cortex responded to moving object stimuli. Visual object recognition can be performed in wide cortical regions including these areas. Analysis of associative auditory responses to visual stimuli revealed that the associative responses were observed in diffuse auditory areas including the anterior auditory field. The formation of associative memory required stimulus complexity, which may be essential for characterizing stimuli. Visual object recognition is related to visual consciousness. Damages to the primary visual cortex (V1) impair visual consciousness. We investigated a male patient with the damaged V1. Repeated presentation of dynamic visual stimuli to him resulted in long-term potentiation in the probability of detection of visual stimuli, and after this potentiation, he could read hiragana letters presented in the impaired visual field.
