(a) Dependence of gain coefficients and (Equations 23) on the strength of the gain fluctuations, determines their effect on the choice correlation for the uninformative stimulus s0. determines the degree of asymmetry of the choice correlation dependence on the . (b) profiles, represented in the same 2-D space as in Figure 4D,E, generated with a uniform sampling of consistent with the observed average CPs of the MT cells, and with a uniform sampling of the gain (). (c) Analogous to b, but with a nonuniform distribution in the 2-D space, reflecting structure in the covariation of and . (d–e) profiles corresponding to the clusters centers obtained when sampling the space according to panels b and c, respectively.
