Abstract

A previous study demonstrated that alcohol markedly shortened the patellar tendon reflex time in human subjects.1 Both it and another study2 indicated that the central nervous system of man enjoys a constant relationship existing between its higher and lower levels. This relationship appears to be in the direction of dominance of the superstructures so that the higher levels of irradiation play a functional part in the lower levels of irradiation—alterations in the former determining a depth effect on the latter. The present comparative study is reported to indicate a similar relationship existing in a central nervous system of a lower developmental order.

METHOD  Again we determined the reflex time with the action current technic. In general, each of five dogs, ranging in weight from 31 to 37 pounds (14.1 to 16.8 Kg.), was given intravenously rapidly 20 cc. of 97 per cent alcohol in 80 cc. of physiologic
