(A) Mutual information rate of the two-state model (solid lines) and general model (dashed lines) of short-term facilitation as a function of normalized input spike rate for various values of baseline synchronous release probability, $p_1$. (B) Similar to (A) for energy-normalized information rates. The simulation parameters are $q_1=0.05$, $u=v=0.5$, $p_{max}=1$, $q_{max}=0.2$, ${\tau }_{{}_{L,p}}={\tau }_{{}_{L,q}}=250$ msec, and ${\tau }_{{}_{f,p}}={\tau }_{{}_{f,q}}=20$ msec.
