Medial region of the amygdala: involvement in adrenal-steroid-induced salt appetite.
We report the following observations: first that cell body damage induced by ibotenic acid within the medial region of the amygdala resulted in the abolition of corticosterone-potentiated, aldosterone-induced salt appetite. Sodium depletion-induced salt appetite was not impaired by the lesion, nor was angiotensin-dependent salt appetite via captopril treatment. These results provide evidence that the medial region of the amygdala has a major role in the natriorexigenic effects of the adrenal steroids.
