“…The reciprocal nature of this control is also indicated by the activation of hypothalamic feeding mechanisms by corticomedial amygdala and its inhibition by the basolateral amygdala. Similar dichotomies can be observed in aggressive behavior (Hilton & Zbrozyna, 1963;Stockman, & Glusman, 1970) and its autonomic components (Bonvallet & Bobo, 1972;Matheson, Branch, & Taylor, 1971).…”

A previous study reported that power in the delta band of the amygdala is selectively elevated when primates are exposed to affectively ladened stimuli (Kling, Steklis, & Deutsch, 1979). Radiotelemetric recordings suggested that this elevation was greatest when the animal was confronted with conspecific behaviors that could be interpreted as "ambiguous." In the present study, a specific elevation of delta activity was observed when the animal was placed in an environment in which uncued shock had previously been received, in relation to environments in which shock had always been cued. This occurred even though the conditioned stimulus or unconditioned stimulus (or both) was not presented. A specific elevation in delta activity also occurred when a conspecific was present, in relation to when the animal was alone. Finally, recordings in an environment in which shock training had previously occurred showed a striking lateralization of delta activity in the right amygdala but not in the cortex. At other times, no lateralization was observed.

“…The most straightforward interpretation of the present data is that the amygdala normally facilitates activity in the nigro-striatal system. It is possible that this influence is mediated by hypothalamic mechanisms, in view of the observation that amygdaloid stimulation facilitates hypothalamically elicited flight responses (Stokman & Glusman, 1970). If this hypothesis is correct, then amygdaloid lesions would result in reduced nigrostriatal activity, which could be restored by drugs that enhance dopaminergic activity.…”

Amygdalectomized and control rats were given 400 active avoidance training trials in a shuttle box. Control animals received 0, 4, 8, or 16 mg/kg of methylphenidate throughout acquisition. Amygdalectomized animals were given the first 200 trials without drug, followed by 200 trials with drug. The administration of methylphenidate produced an abrupt and large improvement in performance in the amygdalectomized animals. One month after acquisition under the drug, retraining without drug revealed a significant rentention effect for the three amygdaloid-drug groups relative to the nondrug-amygdaloid group. These results indicate that although amygdalectomy impairs the performance of avoidance responses, it does not prevent the learning or retention of such responses. Since methylphenidate appears to act primarily on dopaminergic mechanisms, the possible influence of amygdalectomy on such mechanisms is discussed.

Directional interaction of midbrain and hypothalamus in the control of carbachol-induced aggression

Microinjection of carbachol into the ventromedial part of the anterior hypothalamus or the ventrolateral part of the mesencephalic central gray elicits affective aggression in the cat. Pretreatment with atropine in the same site blocks carbachol‐induced aggression. Prior administration of atropine into the midbrain blocks aggression induced by carbachol injections into the hypothalamus, but atropine injected into the hypothalamus does not prevent affective aggression elicited by carbachol administered into the midbrain. The results demonstrate a directional interaction between midbrain and hypothalamus, and provide suggestive evidence for a hierarchal organization of these limbic structures in the control of cholinergically‐mediated affective aggression.
