Figure 5.

Contour plots of mean PM (A) and AM (B) coding fractions as a function of action potential threshold (Vth) and neuronal noise (σn) obtained from 10 model simulations. The bars to the right show the scaling of the contour plots. The values of Vth are in relation to the resting membrane potential, which is arbitrarily set at 0. The left column shows the coding fractions obtained from simultaneous presentation of random AM and random PM, and the right column shows the coding fractions obtained from separate presentation of random AM and random PM.
