Jansen-Rit Neural Mass Model (1995)
JansenRit1995
Description
Lumped-parameter cortical column model with three neural populations: pyramidal cells, excitatory interneurons, and inhibitory interneurons. Each population is modeled by a PSP block (2nd-order linear filter) and a sigmoidal potential-to-firing-rate transformation. The model produces EEG-like output as the pyramidal PSP difference v_pyr = y1 - y2. Based on Lopes da Silva et al. (1974, 1976) and Jansen et al. (1993).
