| Outline of Final Research Achievements |
It has been suggested that the higher brain functions in primates including human are regulated by highly developed cerebral cortex. A large number of researches using primates have actively investigated to clarify the functions of anatomical connections between areas. However, the underlying circuit mechanisms of the higher functions remain elusive, because of the difficulties to generate a method of selectively manipulating the interaction between brain sites. In this research project, we mainly focused on a functional interaction between prefrontal cortex and inferior temporal cortex to regulate attention, and in order to identify circuits and neural activities, we were able to develop a technique to projection-specifically manipulate a gene between two areas, and will apply this to trained monkeys to projection-specifically block a brain function, attention, and then analyze them by behavior and electrophysiological studies.
