Conference paper


Control of the phase coherence between oscillatory neuronal populations has been proposed as a key mechanism to gate neuronal communication. Here we investigate the emergence of phase coherence, at the level of both LFP and MUA, between two neuronal areas that exhibit population oscillations in the gamma band. To that end we simulate two large interacting recurrent networks of Hodgkin-Huxley neurons. We observe that changes in the strength and topology of inter-areal synaptic projections can effectively modulate the phase coherence at gamma frequencies.
