| Outline of Final Research Achievements |
Pre-motor time (PMT) during motor reaction tasks reflects the time needed for processing a sensory stimulus and primarily consists of the time for intracranial processing (visuo-motor related time: VMRT) and neural conduction (motor evoked potential: MEP latency) between the motor cortex and corresponding muscle. The present experiment was to examine the PMT delay using noninvasive technique, such as electromyogram or transcranial magnetic stimulator (TMS). The main findings were: 1) the PMT delay comparatively influences VMRT, but not MEP latency, 2) relative concentration of deoxygenation haemoglobin shows a tendency to increase when VMRT delayed, 3) disturbance input during reaction task by TMS delays the PMT depending on changes in cortical excitability and length of individual VMRT.
