A study was made of the influence on self-stimulation of non-painful sensory stimuli of different modalities, and of intra-brain stimulations of emotionally positive and neutral points with the wiew to elucidate the specificity of certain functional relations appearing during interaction between emotionally negative and positive conditions. The data obtained attest that the influence of various excitation sites on self-stimulation reactions depends not so much on the strength of the stimuli, as on the specific neurophysiological organization of emotionally negative zones in the brain. A reciprocal enhancement of excitation of self-stimulation zones points to a certain non-specificity of positively reinforced structures.

Non-painful sensory stimuli and intra-brain stimulations of emotionally positive and neutral points influence self-stimulation reactions, with the effect mainly dependent on the specific neurophysiological organization of emotionally negative zones in the brain.

Key Takeaway: Non-painful sensory stimuli and intra-brain stimulations of emotionally positive and neutral points influence self-stimulation reactions, with the effect mainly dependent on the specific neurophysiological organization of emotionally negative zones in the brain.
