Abstract

Brain rhythmic activity model on the basis of space uniform neuronal network consisting of excitatory and inhibitory elements was examined. Network activity description by "lump approximation" was compared with simulation model computation. Lump approximation parameters dependence on the properties of neurons and synapses as well as conditions of the transition between network activity types which imitate desynchronous (low voltage fast activity) and synchronous (high voltage slow waves) brain activities were obtained.

摘要

研究了基于由兴奋性和抑制性元件组成的空间均匀神经元网络的脑节律活动模型。将通过“集总近似”对网络活动的描述与模拟模型计算进行了比较。获得了集总近似参数对神经元和突触特性的依赖性,以及模仿脑去同步(低电压快活动)和同步(高电压慢波)活动的网络活动类型之间转变的条件。
