THE EXPERIMENTAL PRODUCTION IN THE CAT OF A CONDITION SIMULATING PSEUDO-BULBAR PALSY

Abstract

[Exps. on 25 cats showed that] bilateral injury of the rostral portion of the cerebral cortex of cats involving the motor area and particularly an area ventrolateral to the electrically responsive motor area controlling the legs, produces abnormalities of feeding, of behavior, and of tone in the extremities with changes in the righting reflexes. The analogy between certain of these changes and the symptom complex of pseudo-bulbar palsy is discussed. The entire syndrome of pseudo-bulbar palsy would seem dependent on bilateral injury of localized areas in the cerebral cortex or of their projection fibers.
