Orthodromic and antidromic components of responses evoked on the pericruciate cortex upon stimulation on the ventral medulla in chronic cats.

Abstract

AbstractThe electrical stimulation of the ventral medulla evokes on the ipsilateral pericruciate cortex a polyphasic response (Woolsey and Chang, 1948; Lance and Manning, 1954; Landau, 1956; Jabbur and Towe, 1961), which appears to be constituted by two (Woolsey and Chang, 1948; Lance and Manning, 1954; Landau, 1956) or three (Jabbur and Towe, 1961) fast positive deflections (labelled as a, b, and c waves by Jabbur and Towe, 1961) followed by a slow positive-negative deflection.
