Recovery of salt appetite after lateral hypothalamic lesions: effects of preoperative salt drive and salt intake experiences.
This study presents further observations on the effects of preoperative salt experiences on salt appetite following lesions of the lateral hypothalamus. The results confirmed earlier findings that preoperative salt experiences can protect the rat against the usual deficit in regulatory salt intake that follows such lesions. However, the results suggested that there may be no specific feature of the preoperative salt experience that is critical for the protective effect since both salt drive experience without concomitant salt intake experience and salt intake experience without concomitant salt drive experience were effective.
