It is shown that unconditional reflex networks, realizing the activity only within a classical physical determinism (Kruglikov R. I. 1988), and transmitting an operating bioelectric signal from a sensory entrance to a moving exit, can realize adequate forms of answers to environmental influences only in the conditions of not changing, routine environment. In the conditions of environmental novelty adequate answers to new influences can realize only neural networks showing the activity within the principle of hierarchical subordination of one neural networks to other neural networks where operating neural networks, integrating information fixed in subordinated neural networks, gain big "information competence" in relation to them. This principle of formed hierarchy of neural networks can be carried out only by means of mental processes as only by means of mental processes operating networks can integrate ontogenetically stored information fixed in subordinated neural networks. Integrating "divorced in past time" information, managing neuronal networks get opportunity adequately ("competently" - i.e. taking into account the integrated past experience) to operate the behavioral answer to a new environmental irritant. In this case synapses are such relay (switching) structures which provide not only transfer of managing signals of bioelectric streams from a sensory entrance to a motor exit in unconditional reflex networks, and not only systemic change of modes of activity of a brain (wakefulness, dream modes). But within a wakefulness mode by means of synapses such redistribution of bioelectric streams in the subordinated neural networks carried out which corresponds integrated in mental processes of operating neural networks of new information necessary for the adequate behavioral answer to novel environmental stimuli.

Synapses, thus, are functionally connected with mental processes.
