title: Vestibular versus tail-pinch activation in cats with lateral hypothalamic lesions.
abstract: Mild tail-pinch induces eating in animals which are aphagic following lateral hypothalamic lesions. This study compares the specificity of the behavior produced by tail-pinch to that produced by vestibular stimulation in cats which are akinetic and aphagic following lateral hypothalamic lesions. In these cats, tail-pinch elicited licking and biting at food while vestibular stimulation preferentially elicited forward locomotion. These results suggest that such stimuli activate specific movement subsystems rather than producing general, nonspecific arousal.
