EVIDENCE OF VASODILATOR INNERVATION IN THE PARIETAL CORTEX OF THE CAT

Abstract
The thermoelectric method of Schmidt and Pierson was used to record changes in blood flow by means of a thermocouple inserted 2 or 3 mm. into the parietal cortex of cats. The flow increased on stimulation of the facial nerve at the geniculate ganglion, thus giving further evidence of a parasympathetic vasodilator innervation of cerebral vessels in this region.
