[Relations between hypothalamic autostimulation and current strength].

In order to examine effects of current intensity of the self-stimulation rate and to study evoked behavioural, somatic, and visceral responses, 105 electrodes were implanted in 35 cats in the lateral hypothalamus. Electrical stimulation produced all kinds of behavioural patterns depending upon both the electrode location and the current intensity. Three types of self-stimulation curves were differentiated on the basis of curve shapes and the maximum rate of self-stimulation.
