Schematic of a biophysical network model.

Resting state brain imaging has seen rapid growth in recent years. However, much of this work has been phenomenological, and hard to relate to neuronal processes. As a result an active area of research is the development of large-scale biophysical network models to gain insight into the underlying generative mechanisms of spontaneous brain activity. These biophysical network models combine knowledge of the anatomical (white matter) connectivity, with models that capture the dynamic behaviour of populations of neurons within the grey matter. These are used to predict the spatio-temporal dynamics of real functional neuroimaging data.
