| Outline of Final Research Achievements |
The purpose of this study is to test a hypothesis that motor command of the arm movement concomitantly produces motor command to the eye movement. Arm movement frequently induced eye motor response when the head was not fixed, but that did not induce eye motor response when the head was fixed. The latency of the eye movement was longer than the latency of EMG response in the arm and that of the head movement. There was no significant difference between the latency of the arm and eye movements. Motor imagery of arm movement and vibratory stimulation over the arm muscle did not induce eye movement. Those findings indicate that eye motor response is originated from optokinetic response caused by head motion artifact due to anticipatory postural adjustment associated with arm movement.
