A01 Elucidation of the hyper-adaptation mechanism by reconstruction of bio-structure and challenges for prevention of decline in latent adaptive capacity
Research Outline

Tadashi ISA
In A01, we primarily address the hypothesis that disinhibition of global neural network underlies the reconstitution of the neural structure as a basis of hyper-adaptability. We aim to unravel the mechanism of disinhibition of the neural network through analysis of the rodent, monkey and human brains and propose an effective strategy for functional improvement based on the evidence for the age-related functional deterioration. The mechanism underlying the global disinhibition in the brain is uncovered through long-term and longitudinal analysis of neural and muscular activity in the monkeys before and after the spinal injury using electrocorticography and electromyography. Pathway-specific manipulation and recording in rodents provides the neural substrate which accounts for how the dopaminergic and serotonergic diffuse modulatory system mediate the disinhibition of the global neural networks. Functional magnetic resonance imaging study reveals chronic disinhibitory state in the aged human brain and proposes effective training methods which improves functional deterioration using age-related progress and magnitude of neural disinhibition as an indicator.
