“…Source space projection can be done with commonly used software packages (e.g., the open-source Matlab toolbox FieldTrip or BrainStorm or the commercial products BrainVoyager or Besa) by inverting a forward solution on the basis of given source dipole positions and orientations and a volume conductor model; all of the above can be individually estimated from anatomical MRI data of subjects (Chan et al, 2009 He and Liu, 2008;Liu and He, 2008;Michel et al, 2004;Pascual-Marqui, 1999)]. …”

Brain function is thought to emerge from the interactions among neuronal populations. Apart from traditional efforts to reproduce brain dynamics from the micro-to macroscopic scales, complementary approaches develop phenomenological models of lower complexity. Such macroscopic models typically generate only a few selected-ideally functionally relevant-aspects of the brain dynamics. Importantly, they often allow an understanding of the underlying mechanisms beyond computational reproduction. Adding detail to these models will widen their ability to reproduce a broader range of dynamic features of the brain. For instance, such models allow for the exploration of consequences of focal and distributed pathological changes in the system, enabling us to identify and develop approaches to counteract those unfavorable processes. Toward this end, The Virtual Brain (TVB) (www.thevirtualbrain.org), a neuroinformatics platform with a brain simulator that incorporates a range of neuronal models and dynamics at its core, has been developed. This integrated framework allows the modelbased simulation, analysis, and inference of neurophysiological mechanisms over several brain scales that underlie the generation of macroscopic neuroimaging signals. In this article, we describe how TVB works, and we present the first proof of concept.
