THE EFFECT OF HYPOPHYSECTOMY ON AVOIDANCE BEHAVIOR AND ON MOLECULAR NEUROCHEMISTRY.

Abstract

Two shock avoidance conditioning experiments were conducted to determine the effects of hypophysectomy on conditioning and on brain neurochemistry. The dependent variables were: number of avoidances, latency, and trial of first avoidance; amounts of RNA, DNA, and proteins; ratios of these three; the specific activity of protein and tissue pool fractions; and the relative specific activity of the protein fraction. There was a tendency for hypophysectomized rats to show fewer avoidances. As in previous experiments there was a suggestion that the medial and posterior ventral cortices may contribute to this type of conditioning. (Author)
