[The structure and transcription activity of the neuronal chromatin in the sensorimotor cortex during postnatal differentiation].

We report findings about age-related changes in the chromatin structure detected using ammoniacal silver and changes in the transcription rate in neurons by layers II-V of the sensomotor cortex of rats at days 7, 14 and 60 of postnatal life. Different types of neurons showed different average template activity but similar patterns of its age-related changes. The rearrangement of the chromatin structure in various types of cortical cells showed different orientation after day 14 of postnatal life.
