Cortical activity after stimulation of the corticospinal tract in the spinal cord

Highlights • After electrical stimulation of the spinal cord, two types of evoked potentials over the scalp were detected; early and late potentials. • The early potential had a feature of antidromic stimulation of the corticospinal tract (“anti D-wave”) while the late potential exhibited orthodromi...

Summary:Highlights • After electrical stimulation of the spinal cord, two types of evoked potentials over the scalp were detected; early and late potentials. • The early potential had a feature of antidromic stimulation of the corticospinal tract (“anti D-wave”) while the late potential exhibited orthodromic stimulation of the dorsal columns. • We extensively examined early potentials recorded over the scalp and provide evidence of antidromically stimulated fast neurons in the corticospinal tract.
