[Integrative properties of the microsystem of cortical neurons during repeated local stimulation].
Small groups of neighbouring neurons in neocortex are able to form separate microsystem in model situation of habituation during the local repetitive action of acetylcholine. This new functional unit exhibits a number of main properties which are characteristic of systemic processes of habituation. Only some of the properties don't reproduce in microsystem of cortical neurons. There is no effect of full extinction of responses and no direct relationship between the decrease of speed quantity of responses and stimulus action frequency. The data obtained are considered as significant argument for identification of special intermediate level of integrative processes--microsystem level.
