Abstract

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.

摘要

在乙酰胆碱局部重复作用的习惯化模型情境中,新皮层中相邻的小群神经元能够形成独立的微系统。这个新的功能单元展现出许多习惯化系统过程所特有的主要特性。只有部分特性在皮层神经元微系统中未重现。不存在反应完全消退的效应,反应速度量的降低与刺激作用频率之间也没有直接关系。所获得的数据被视为识别整合过程特殊中间水平——微系统水平的重要论据。
