Regularities of Alternate Behavior in Spontaneous Nonconvulsive Seizure Activity in Rats

275 The study of the complicated behavior of ensembles of neuronal elements is of great interest. In this connection, the brain, which is a very complicated neuronal ensemble, is an interesting object for investigation. The brain research is of theoretical interest and has a great importance because the study of fundamental laws of brain function helps to find the reasons of origin and development of pathologies in the central nervous system [1]. Processes in the brain are often studied using approaches based on the construction of relatively simple models of single neurons [2], which are subsequently connected together [3]. The next stage in the development of the models in question is the consideration of chains, lattices, and networks consisting of elements that model single brain structures [4]. Evidently, the results obtained using such models should be compared with the results obtained in the experiments. Another approach is the study of experimental time series and their analysis by methods of nonlinear dynamics [5, 6]. In particular, it is worth mentioning the report [7] in which the authors attempted to determine the direction of the links between different regions of the brain cortex to diagnose their functional interaction.
