Figure 1

Partial bifurcation diagram of the mean-field model. A periodic solution (blue) bifurcates from an equilibrium (black), both spatially homogeneous. The primary instability, however, is a Turing bifurcation to the pattern in the left inlay. The second inlay shows the power spectrum of the excitatory membrane potential at one point in the domain, with a peak at 40Hz as well as resonance peaks. The periodic solution was computed with 1mm resolution.
