| Outline of Final Research Achievements |
Possible effects of oscillatory neural activity on the neural transmission have been examined using mathematical models. Specifically, estimation of parameters of a model of short-term synaptic plasticity has been done for corticospinal synapses based on the data in the literature, and synaptic transmission was examined by using spike timings obtained from simulation results of a model of cortical (visual cortex) cell. It was found that average transmission (post-synaptic potential) per pre-synaptic spike can become small when apical tuft dendrites of pre-synaptic cortical cell receive inhibitory inputs that oscillate as a population at the beta frequency compared with the cases where inhibitory inputs oscillate at different frequencies or do not periodically oscillate.
