  • LEARN: Neural Masses as Source Models for EEG and MEG

    • Basics

    The concept of neural masses, an application of mean field theory, is introduced as a possible surrogate for electrophysiological signals in brain simulation. The mathematics of neural mass models and their integration to a coupled network are explained.

    Bifurcation analysis is presented as an important technique in the understanding of non-linear systems and as a fundamental method in the design of brain simulations.

    Finally, the application of the described mathematics is demonstrated in the exploration of brain stimulation regimes.
