Abstract

Current neural network models are far beyond the physiology of cerebral cortex neurons. Brain models based on neurodynamics consider neurons asdynamical systems. And as such, they seek to understand and represent the reasons why neurons are excitable cells. The microscopic current from each neuron sums with currents from other neurons, which causes a macroscopic potential difference, measured with the electroencephalogram (EEG). EEG records the activity patterns of mesoscopic neuron populations. A good neuronal model must reproduce the dynamics of neurons: in this approach, the information processing depends not only on the electrophysiological properties of neurons, but also on their dynamical properties.
