| Outline of Final Research Achievements |
Our eyes move rapidly and with an extremely high frequency of several times per second. Yet we are able to perceive the visual world as stable and continuous despite our eye movements, unlike camera's blur. How does our brain deal with the blurry retinal images resulting from self-eye-movements? In order to understand the neural mechanisms of the visual stability irrespective of eye movements, we recorded and analyzed neural activity in the MST area, which is part of the posterior parietal cortex of macaque monkeys. We have clarified that the MST area contributes to compensate for the retinal image motion induced by smooth pursuit eye movements, and also to recall visual information, that have pre-existed before saccadic eye movement, after the eye movement.
