The mechanisms of combination of cortical neurons into discrete modules or elementary ensembles, serving as functional units and forming a mosaic of activity in which incoming information is coded, have been investigated. Neurons activated primarily by terminals of specific afferents respond stably with a minimal latent period and become the centers of ensembles, whose periphery is formed by secondarily activated neurons, responding variably with a longer latent period. The stochastic participation of these neurons in the structure of the ensembles lies at the basis of plasticity of cortical mechanisms. Neurons inhibited intracortically, and possibly, via ascending inhibitory pathways, are concentrated at the periphery and near the output cells of the ensemble.
皮层神经元组合成离散模块或基本集合体的机制已得到研究，这些模块或集合体作为功能单元，形成了一种活动镶嵌模式，其中传入信息被编码。主要由特定传入神经末梢激活的神经元以最短潜伏期稳定反应，并成为集合体的中心，其周边由次级激活的神经元形成，这些神经元反应变化较大，潜伏期较长。这些神经元在集合体结构中的随机参与是皮层机制可塑性的基础。皮层内受抑制的神经元，可能还通过上行抑制通路，集中在集合体的周边和输出细胞附近。
