| Outline of Annual Research Achievements |
Innate fear is a type of negative emotion that even if one did not learn or experience before, one is afraid of it. For animals, this is related to survival, because they have to know their predators before experiencing to be captured. Until now, the neuronal mechanisms of innate fear in primate are still largely unknown.With the support of Kakenhi research start-up funding, I am performing a series of experiments trying to reveal the origin of visual innate fear and the potential neural networks with full hemifield ECoG recording in a small new world monkey, the common marmoset. I am also developing optogenetic manipulation method to preturb the network for causality measurments.I expect that I can clarify the neuronal networks and brain regions that are related to visual innate fear.
