| Outline of Final Research Achievements |
Systemic injections of yohimbine, an α-adrenoceptor antagonist, selectively increase the consumption of a highly preferred sweet liquid food but not the normal chow in rats. Temporary inactivation of the basolateral nucleus of the amygdala by a pharmacological treatment abolished the facilitatory intake of a preferred food by yohimbine. Since yohimbine is known to evoke a mild stress, it is suggested that neural circuits including the basolateral nucleus of the amygdala have a pivotal role for overconsumption of highly preferred food under a weak stress condition in general.
