| Outline of Final Research Achievements |
Flexible silk electrode fabricated based on PEDOT was surgically inserted to record the electromyographic (EMG) activity of rat gastrocnemius muscle. By means of implanted telemetric system, stable EMG activity of a free moving unrestrained and unanesthesized rat was recorded over the period of 3 weeks. EMG activity after the muscle damage induction by intramusclular injection of venom toxin, cardiotoxin, was recorded over the period of 1 week. The observed EMG changes was in accordance with the time course of previously known histological damage and recovery.
