Information (in Bits) Versus Synaptic Drive, μ.

Red: the probability of a presynaptic spike, p, is 0.5, corresponding to an effective presynaptic firing rate of 50 Hz, assuming a time bin of 10 ms. Blue: the probability of a presynaptic spike is 0.01, corresponding to an effective presynaptic firing rate of 1 Hz. Noise levels, σ, are 0.0, 0.1, 0.2, and 0.5 (thin to thick lines). The threshold, θ, was set to 1.0.
