From: Divergence alone cannot guarantee stable sparse activity patterns if connections are dense

Regions where our criteria 1–3 are fulfilled. Dark blue: none are fulfilled, blue: (3) is true, light blue: (2) is true, cyan: (2) and (3) are true, yellow: (1) and (3) are true, orange: (1) and (2) are true, and red: all three are true. Note that for no gain control (A), the red region is located between p c = 0.1 and p c = 0.3 and is very thin. It then moves to higher p c with increasing gain control (B), (C) and (D), where it disappears. The strings of white dots in each of the panels mark the locus of the minimum of the probability of confusion with respect to the threshold θ KC for each given value of p c Depending on the density of connections, a different degree of gain control is necessary to be able to fulfill all three criteria for a suitable sparse activity.
