Outline of Final Research Achievements

To develop a brain-machine interface system, which enables to send artificial information to higher brain areas, in this study we attempted to manipulate columnar neural activities of monkey inferior temporal cortex encoding visual object information. As a tool to manipulate neural activities, electrical microstimulation was adopted to activate specific object columns forcibly. As a result, we succeeded to make the animal percept electrically-created-visual objects that were virtually non-existent during delayed matching to sample test.
