Abstract

Conditioned taste preferences were produced in rats presented with a novel taste followed by a session of intracranial self-stimulation. The size of these preferences varied as a function of the intensity (i.e. reward-strength) of the stimulation. While self-stimulation response rates were reduced by the motoric side-effects of high intensity stimulation, taste preferences were not. It was concluded that the taste preference paradigm may provide a useful measure of brain-stimulation reward that can be applied in situations where rate measures are inadequate.
