[The neuronal ensembles of the brain].
The conclusion about availability of two types of neuron ensembles in the central nervous structures was made on the basis of proper experimental studies and appropriate literature data analysis. The first is presented by neurons functional cooperation (Hebbian ensembles) formed during learning process on the basis of synchronization by high-frequency oscillator activity. The second is presented by morphological-and-functional structures (Kogan's neuron ensembles) formed during neurogenesis process and genetically destined for biologically valuable patterns recognition. The control of functional state of the brain neuron networks and occurred information processes is realized by non-specific systems either restrict the neurons capability of joining in the rate of global synchronization by synchronization and desynchronization actions or form and maintain the common rhythm of activity in considerable neuron populations. The latter block single elements ability to enter into specific interactions.
