[Motor conduction time of the corticospinal tract in spinal stimulation].
A muscular action potential (MAP) following transcranial and spinal stimulation can be recorded from most of the striped muscles. The motor central conduction time after transcranial and spinal stimulation can be determined at cervical 6/7. It is at 5.0 ms in normal subjects. This was demonstrated in four normal subjects. After spinal stimulation at cervical 6/7 a motor evoked potential can also be recorded from the scalp. It has a latency that is comparable to motor conduction time. In animal experiments in examining ten rabbits a motor evoked potential to stimulation at several levels of the spinal cord could also be determined.
