Together these experiments provided strong support for endogenous feedback electric fields playing an active role in shaping (synchronized) cortical network dynamics. Detailed biophysical modeling of such cortical networks exposed to activity-dependent electric fields further validated these findings. Therefore, the endogenous electric fields generated by structured cortical network activity may be more than an epiphenomenon, but rather may play an active role as a neuronal communication mechanism.

endogenous electric fields can enhance rhythmic cortical network dynamics
