Description
The Jansen-Rit is a neurophysiologically-inspired neural mass model of a cortical column (or area), developed to simulate the electrical brain activity, i.e., the electroencephalogram (EEG), and evoked-potentials (EPs; Jansen et al., 1993; Jansen & Rit, 1995). It is a 6-dimensional, non-linear, model describing the local average states of three interconnected neural populations: pyramidal cells (PCs), excitatory and inhibitory interneurons (EINs and IINs), interacting through positive and negative feedback loops. The main output of the model is the average membrane potential of the pyramidal cell population, as the sum of the potential of these cells is thought to be the source of the potential recorded in the EEG.
