摘要

提出了一个由兴奋层和抑制层组成的结构中的非线性均匀扰动的功能失调脑干活动模型。皮层脑电痕迹与兴奋细胞活跃部分的时间导数相一致。层间时间延迟的增加引起周期性非线性振荡的开始。生化状态的改变会引起类似癫痫发作的快速振荡。

A continuum model of activity waves in layered neuronal networks: computer models of brain-stem seizures

A model of dysfunctional brain-stem activity as nonlinear homogeneous disturbances in a structure consisting of excitatory and inhibitory layers is presented. Cortical EEG traces are identified with the time derivative of the active fraction of excitatory cells. Increase in the time delay between the layers causes the onset of periodic nonlinear oscillations. Change in the biochemical state can cause rapid oscillations similar to seizures.<>
