โœฆ Synopsis

Dogs, rhesus monkeys and rats were trained to avoid electric shock by using different discrete conditioned avoidance response procedures. Chlorpromazine selectively blocked avoidance behavior in the rat, but non-selectively blocked both avoidance and escape behavior in the dog and monkey. Morphine was selective against avoidance behavior in the rat but was inactive in the dog and monkey. Pentobarbital and meprobamate non-selectively blocked both avoidance and escape performance in all three species. These data, when compared with literature reports, support the conclusion that selective antiavoidanee activity is not an intrinsic property of the chlorpromazine or morphine molecule.

In this study, an operant conditioning and extinction technique is used to compare the effects of various so-called tranquilizing agents. In addition, a method is presented for the preparation of 2-ethyl-2-(3-methyl)-butylrnalondiamide. The statistical analysis of the data obtained is supported by o
