THE EFFECTS OF SOME CENTRAL NERVOUS SYSTEM DEPRESSANTS ON CONFLICT BEHAVIOR IN DOGS

Abstract

Phenobarbital, pentobarbital, thiopental, meprobamate and ethanol restored the inhibited food taking response, but benactyzine and chlorpromazine did not produce the restoring effect. Before inducing conflict behavior, phenobarbital did not abolish the conditioned food taking response even in such large doses as caused severe ataxia and sometimes falling, although the dogs frequently failed to press the bar exactly. Benactyzine and chlorpromazine abolished the conditioned food taking response, and in the doses almost abolishing the conditioned food taking response, the former caused dogs to walk about in the experimental cage and the latter to lie down.
