Fig 2. Dependence of firing rate and good area on LGN synaptic strengths.

A 3 × 4 matrix of panels is shown: each row corresponds to a fixed value of S^Ilgn/E^lgn and each column a fixed value of S^Elgn/S^EE. Each panel shows a heat map for f_E on an inhibition plane (color bar on the right); x and y-axes are as in Fig 1. Good areas are in white, and their centers of mass marked by black crosses. The picture for S^Elgn/S^EE = 2 and S^Ilgn/E^lgn = 2 (row 2, column 2) corresponds to the f_E rate map in Fig 1. Other free parameters are S^EE = 0.024, S^II = 0.12, and F^IL6 = 3 × F^EL6.
