The effects of ethanol upon threshold and response rate for self-stimulation.

The hypothesis that ethanol would reduce the threshold for self-stimulation of the medial forebrain bundle was not supported. Ten rats, implanted with electrodes in the lateral hypothalamus, were shaped to bar press for electrical brain stimulation. The effects of 0.6, 0.9, and 1.2 g/kg ethanol injections upon threshold and response rate for self-stimulation were measured. The lowest dose had no effect upon self-stimulation threshold while 0.9 and 1.2 g/kg ethanol raised thresholds. Rate of bar pressing was increased by 0.6 g/kg ethanol but was not affected by higher doses. Results were discussed in terms of a postulated dual effect of ethanol upon a brain arousal system and upon a reward system.[1]
