About the Neuronal Mechanism of Lateral Hypothalamic Self-Stimulation Response

TL;DR

This study investigates how electrical stimulation of the lateral hypothalamus influences hunger and positive emotions, revealing that stimulation duration affects the type of motivation or emotion elicited, supporting an adaptation theory of motivation.

Contribution

It demonstrates the differential effects of stimulation duration on hunger and positive emotions, providing insights into the neuronal mechanisms of motivation and emotion.

Findings

Long-term stimulation evokes hunger motivation.

Short-term stimulation induces positive emotions.

Supports adaptation theory of motivation and emotion.

Abstract

The experimental part of this study has shown that hunger motivation may be evoked by a long-term (10=180 s) continuous electrical stimulation of the "hunger center" at a current of 133.6{\pm}8.1 mkA. Positive emotions were caused by electrostimulation at the same current intensity but short-term duration (0.3-0.5 s). A positive feeling elicited by electrostimulation of the motivation center can be explained in terms of the adaptation (polarization) theory of motivation and emotion (Murik, 2001, 2005).
