Figure 1

Contour plot of slopes of response curves in numerical experiments using rate model neurons (A) and mean field equations (B). We plot the derivative of change in the PN activity with respect to the external stimulus as a function of α which is the fraction of excitatory neurons that receive input, and p^EI, which is the probability of having a connection from an inhibitory neuron to an excitatory one. Perfect gain control corresponds to 0 slope and is represented by the thick black solid line in both panels.
