Effect of medial septal lesions on conditioned taste aversion in the rat.

Rats that had sustained lesions of the medial septum developed a conditioned food aversion to sweetened condensed milk at the same rate as controls. This aversion was produced by post-ingestion administration of lithium chloride in ascending doses given on alternate days. Although development of the aversion was the same in lesioned animals as in controls, recovery from it was more rapid in the lesioned animals.
