Abstract
Previous experiments using a sequence of alternating unilateral stimulations of the amygdalae indicated an “oscillation effect”, i.e., consistent low-latency values for convulsions elicited from one amygdala and consistent high-latency values for convulsions elicited by stimulation of the contralateral amygdala. The present study was concerned mainly with statistical evaluations of the reliability of oscillation events. Tests of the randomness of the observed primary and secondary oscillation patterns indicated that oscillation patterns were significant systematic ones in latency, criterion, and duration data, with the greatest frequency of oscillation occurring in the latency measure. Although there was no significant difference in the frequency of primary or secondary oscillation using chi-square methods, an analysis of variance trend analysis indicated that the primary oscillation pattern (low values on primary side) was the predominant one when considered over the total sample, 139 rats. Also, it was shown that the behavioral pattern (oscillation, nonoscillation) appears not to be related to the number of trials to reach the criterion of six convulsions. The exact basis for oscillatory behavior is unknown. However, for a number of reasons, it appears to be based probably on transfer and interference effects between the primary and secondary brain sites.
