As it was shown previously (Serkova, Nikolskaya, 2011) the spatial novelty in adult stage can trigger the sensitive state, very close to the early ontogeny sensitive state (Brainard, Knudsen, 1998), making possible the imprinting of spatial information. In neuroscience the phenomenon of novelty, manifested in the orienting reaction, is regarding as an automatic result of disparity between neural stimulus model and altered parameters of current stimulus (Sokolov, 2003). In the context of the expectation model as a result of unexpectedness (as a form of novelty) inducing disparity between the expected result and the current situation is a result of the mental processes (Tolman, 1932). It would be interesting to determine the level at which the mismatch leads to a distorted reading of the proposed structure of the problem: at the level of mental image or at the level of a physiological description of the stimulus (the alphabet).To answer this question, we placed adult mice BALB/c (n = 30) and F1 of S57BL/6J and DBA/2J (n = 30) into a complex maze with a possibility alter spatial configuration rapidly. As opposed to control, experimental animals faced with an unexpected short-term spatial restructuring in the first session.
An unexpected change in structure of the maze in sensitive period influenced on the route realization of final structure of habit, but this operation didn't disturb the cognitive dynamics, nor the formation of the program behavior. According to the structure of the problem, it was necessary to leave the spontaneous food environment and return to it again in order to be able to repeatedly get reinforcements. However, the experimental animals were trying to combine the instinct spatial preference (direct pathway) with the acquired in a whole decision, although such performance does not satisfied to principle of least action.
However, this structure had been reproduced steady during all the study. Moreover, it showed high stability to a break in work and to process inhibition. The carried out research from the information point of view testifies, that the state of novelty is necessary condition for formation of model of environment (Gestalt) through a designation of consist elements (alphabet). The unexpected spatial influence which has emerged during this sensitive period, allows to expand the alphabet and to become the factor of fluctuation of the behavioural answer taking into account the indignations at a stage of stabilization conditioned process. The data obtained allows to conclude that there is no contradiction between the concepts of neural model of stimulus and expectation one, because they reflect different aspects of the whole psycho-physiological functioning of the brain.
