[Mechanisms of formation of brain cortex background activity in ontogenesis].

Background activity of brain cortex neurons in ontogenesis appears very early, soon after completion of their migration. At the moment of its appearance, the background has several peculiarities, the most characteristic of which are its episodic character and synchronous fires of adjacent neurons forming domains. This paper considers mechanisms determined the appearance and the most characteristic peculiarities of the background of cerebral cortex neurons in ontogenesis.
