Plasma studies depict collisionless, collective movements of charged particles. In touch with these concepts, originally developed in the far flung branch of high energy physics, here we evaluate the role of collective behaviors and long-range functional couplings in brain dynamics. We develop a novel, empirically testable, brain model which takes into account collisionless movements of charged particles in a system, the brain, equipped with oscillations. The model is cast in a mathematical fashion with the potential of being operationalized, because it can be assessed in terms of McKean-Vlasov equations, derived from the classical Vlasov equations for plasma. We also provide insights into the possible role of the overrated extracellular neuronal space in generating and transporting the charged particles which display such a collective behavior. A plasma-like brain also elucidates cortical phase transitions in the context of a brain at the edge of chaos and describes the required order parameters. In sum, showing how the brain might exhibit plasma-like features we go through the emerging concept of holistic behavior of nervous functions.
