Abstract

Rats with bilateral lesions of the anterior prepyriform cortex or medial amygdala demonstrate attenuated behavioral sensitivity to a dietary threonine-imbalance. While rats with medial amygdaloid lesions demonstrate an attenuated ability to acquire taste-avoidances, such a deficit is not found in rats with lesions of the anterior prepyriform cortex. The effect of anterior prepyriform and medial amygdaloid lesions on behavioral sensitivity to dietary amino acid imbalances is discussed in terms of the probable roles played by these areas in amino acid intake control.
