[Relation of alcoholic motivation to the functional state of the emotive zones of the brain in rats].
Reactions of neurones pair of positive and negative emotiogenic hypothalamus zones to electrocutaneous stimulation and to intraperitoneal administration of ethanol solution (2 g/kg) were studied in outbred male rats with previously determined attitude to alcohol. In animals who preferred alcohol the neurones of the negative zone were significantly more reactive, and in animals who preferred water the neurones of the positive zone were more reactive. In both studied groups of rats, in most cases ethanol had an inhibitory influence on impulse activity of negative zone neurones, but it acted differently on positive zone neurones: in most cases it intensified neurones impulse activity in rats preferring alcohol and significantly inhibited it in animals rejecting alcohol.
