Practical 6: Ben-Yishai network of visual cortex
... d) Take λ0 = 5, λ1 = 0, ϵ = 0.1. This means that there is uniform recurrent inhibition. Vary the contrast c (range 0.1 to 10) and observe the steady state. You will see three regimes: no output, a rectified cosine, and a cosine plus offset. e) Next, take a small value for ϵ, take λ0 = 2, and vary λ1 ...
