Short description of important scientific result: A convenient and accessible complex for simultaneous electrophysiological and optical studies of the brain in vivo has been developed and published
Using the example of the barrel cortex, it is shown that the somatosensory cortex does not have a clear functional topographic organization during the first 2-3 after birth, and full functional correspondence occurs in the second half of the critical period of somatosensory cortex development.
Using the example of the barrel cortex, it is shown that the functional significance of spindle oscillations in the somatosensory cortex of newborn rats during the critical period of development lies in the synchronization of the evoked activity of neighbouring cortical areas at the dominant frequencies of spindle oscillations.
The method of internal optical signal for studying the activity of the cerebral cortex in newborn rats under the normal and pathological (epilepsy) conditions was introduced.
