Anticipation for non symmetric gap junctions. Top. GCell anticipation time and maximum firing rate as a function of the gap junction velocity \(v_{\mathrm{gap}}\). Bottom: response curves of GCells corresponding to the three regimes: (A) \(v_{\mathrm{gap}} = 0.6~\text{mm/s}\), (B) \(v_{\mathrm{gap}} = 3\) \(\mathrm{mm}/s\), (C) \(v_{\mathrm{gap}} = 12~\text{mm/s}\). The curves display 3 main regimes (see text): In (A) \(v_{\mathrm{gap}} < v\) and the positive front propagates at the same speed as the pooling voltage triggered by the stimulus; In (B), \(v_{\mathrm{gap}} = v\), the positive front and the negative fronts both propagate at the speed \(v_{\mathrm{gap}}\) and the amplitude of the positive front (\(V_{{G}}(t)\)) increases with t; In (C), \(v_{\mathrm{gap}} > v\) and the positive front propagates faster than the stimulus so that the peak of activity arises earlier. The negative front propagates at the stimulus speed
