Outline of Final Research Achievements

To investigate neural mechanisms for detecting and integrating visual motion, we exposed various moving visual stimuli to human subjects, monkeys and mice, and analyzed their ocular responses. For a further understanding, we recorded neuronal activities in the cortical areas MT and MST of monkeys. The results indicate that most MT/MST neurons were tuned for spatial and temporal frequencies of motion stimuli, and the optimal spatial frequency for MST neurons was lower than for MT neurons, suggesting spatial integration between the areas.
