The spatial organization of biopotentials in the cerebral cortex of 23 subjects who were students at the Faculty of Graphic Arts (“professionals”) as well as 39 subjects lacking systematic experience of visual images (“non-professionals”) was compared with the aim of identifying EEG correlates of the experience of visual images (image formation) in humans.(More)
The characteristics of the spatial organization of biopotentials in the neocortex during the mental creation of original and standard mental images were studied. Intra-and interhemisphere coherence associations at different EEG frequency ranges were assessed, along with linkages between relative changes in measures of linear (correlation coefficient) and(More)
Features of spatial organization of neocortical potentials during mental creating of the original and standard visual images were studied. Intrahemispheric and interhemispheric coherence in different EEG frequency bands and temporal relations between relative changes in the index of linear (correlation coefficient) and non-linear (multiple entropy)(More)

Temporal analysis of changes of pyramidal tract response on the model of prolonged potentiation revealed the significant role of the mechanism of increase of the cell general excitability at the initial stage of trace processes formation ("dominant" analogue) what probably contributes to better consolidation of basic CR mechanism--the increase of synaptic(More)

Changes of pyramidal tract (PT) response after short tetanization, similar to natural stimulation conditions, were analysed in unanaesthetized and nonimmobilized rabbits. PT response recording revealed a long-term (1 h and more) potentiation of monosynaptic neocortical reactions. Predominant better expressed and more preserved increase of synaptic (N)(More)
A conception is advanced according to which synchronization and the cooperative interaction of plastic processes at the level of the individual cell and of cell units of varying degrees of complexity form a principle of cerebral integration. The triggering and unfolding of plastic reorganizations which take place with the participation of(More)
Pyramidal tract response (PTR) was recorded from unanaesthetized rabbits. The following three experimental paradigms were used which imitated behavioural conditioning procedures: pairing of direct stimulation of two cortical points; similar pairing conjoint with stimulation of additional reinforcing the lateral hypothalamus (LH); LH stimulation in response(More)

In experiments with noncurarized and unanaesthetized rabbits was recorded pyramidal tract response in the course of conditioning of direct stimulations of the two points of the cortical surface. The data obtained point to temporary specificity in manifestation of the membrane and synaptic plasticity, to participation of these mechanisms in the processes(More)
