Research Interests

Long time ago, Descartes advanced the mind-body dualism, which says that the ego and the spirit exist separately from the flesh in this world. Is this theory correct? Or, is it wrong? To neurophysiologically answer this question, we conduct studies with respect to causal relationship between neural activities and mental states by setting questions as 1) whether neural activities generate mind and 2) whether changes in neural activities are related to those in states of mind. To investigate neural activities at a single neuron level, a local neural circuit level, and a wide-range neural circuit level, we utilize various research procedures. In addition, we estimate mental states of animals from their behaviors using psychological behavioral tasks. By analyzing neural activities in a certain mental state from various aspects, we would like to comprehensively clarify details of neural mechanisms that generate the “mind”.
