Abstract

Fourteen rats were trained to bar press for a series of lateral hypothalamic rectangular pulses and then the threshold of self stimulation was measured in 20 effective loci. Nine loci belonged to rats bearing a bilateral lesion of the terminal stria and 11 self stimulation points served as controls. It was found that the LH current levels needed to produce self stimulation were lower in the rats having terminal strial lesion than in the control animals with no lesion. This finding suggests the existence of an inhibitory structure the localization of which corresponds to that dorsal diencephalic region where terminal stria fibres are found.
