[Latent foci of excitation and the unpredictability of behavioral reactions].

As a model for studying of "subconsciousness" mechanisms, latent foci of excitation may serve formed in animals under different influences on the brain: direct current, endogenous shifts and also under trace excitation after suprathreshold activity. It is experimentally shown that latent foci of excitation can intensify at activation of other CNS areas; as a result externally unmotivated "unpredictable" behavioural reaction arises. Between two latent foci of excitation associative connection can be established. The latent foci of excitation in the human CNS are also able to be activated under the influence of sensory stimuli, and behavioural reaction arising as a result of summation has no reflection in consciousness. Conclusion is made: it is rightful to consider the dominant foci of excitation formed at the level of subconsciousness as one of possible mechanisms of "unpredictability" of behaviour.
