| Outline of Final Research Achievements |
We studied the motor cortical synaptic plasticity in human to elucidate pathophysiological mechanisms underlying neurodegenerative disorders, using a new non-invasive repetitive transcranial magnetic stimulation technique, quadripulse magnetic stimulation (QPS). First, we showed that inter-individual variability was lower in the plasticity induced by QPS than those by the other non-invasive brain stimulations in healthy volunteers. Second, we revealed that the degree of long term potentiation (LTP)-like effects induced by QPS was significantly smaller in the older participants compared to the younger participants. Third, we presented that zonisamide, one of anti-parkinsonian drugs, enhanced LTP-like effect induced by QPS in non-responders to QPS. We presented these data in academic congresses and published those in international academic journals.
