[Neuronal spike activity in the sensomotor region of the cerebral cortex upon direct stimulation of emotionally "positive" and "negative" zones of the hypothalamus].
The effect of electrical stimulation of emotionally positive and negative hypothalamic areas on the unit activity of the sensorimotor cortex in rats was studied in order to elucidate physiological mechanisms of emotions as an important factor organizing purposeful animal behaviour. It was found that such an effect is primarily of inhibitory nature and that it does not carry specific information on biological sign of emotion. It is suggested that the formation of adequate behavioural reactions in different emotional states occurs at earlier stages.
