Direction-selective motion discrimination by traveling waves in visual cortex

Bifurcations in the E-I-E model under differential stimulation.
A: Schematic of the model. B: Responses to identical stimulation Je1 = J + Δ and Je2 = J − Δ where Δ = 0. C: Responses in Ue1 (upper panel) and Ue2 (lower panel) to weakly biased stimulation (Δ = 0.03). D: Responses to moderately biased stimulation (Δ = 0.2). Solid lines indicate stable fixed points. Dashed lines indicate unstable fixed points. Shaded regions are the envelopes of limit cycles. BP is branch point. H is Hopf bifurcation. LP is limit point.
