M.D., Ph.D. Professor Tadashi Isa
Our group double as the Evolutionary Systems Neuroscience Group of the Institute for the Advanced Study of Human Biology (WPI-ASHBi). The group aims at elucidating the neural circuit mechanisms for control of dexterous motor actions and their recovery after the neural injuries and cognitive functions such as decision making and motivation, emotion, attention, associative learning and consciousness and their disorders. We are conducting the researches in various animal models for this goal, applying multidisciplinary methods, such as electrophysiology, psychophysics, neuroimaging, transgenic animals, viral vectors, and computational modeling.
Research and Education
The brain regulates the sensory, motor and cognitive functions by multi-hierarchical network of neural cells. To understand the brain functions, it is necessary to decipher the functions of individual neurons and synapses, local circuits, their large-scaled networks, behaviors, their underlying algorithm of the network operation and their relationships. For this purpose, we combine multidisciplinary methods, such as electrophysiology, neuroanatomy, psychophysics, neuroimaging, transgenic animals, viral vectors, and computational modeling, particularly in the macaque monkey model of brain and spinal cord injury and neural disorders. Macaque monkeys are suitable for the purpose of our study, because they have similar neural systems and body plants to humans. In our laboratory, the PhD students are trained to acquire the disciplines and techniques as neurophysiologists and skills to communicate with scientists from other disciplines at a global scale.
