Fig 5. PC phase modulated by timescales of short-term dynamics of GC-PC synapses.

(A) Histograms of spikes in GCs (top) and PCs (bottom) in response to an input spike train sinusoidally-modulated at 10 Hz, with three examples of time constants of recovery τ_rec (fixed τ_fac = 400 ms) and facilitation τ_fac (fixed τ_rec = 50 ms). (B) Phase shift as a function of input frequency for (left) τ_rec and (right) τ_fac, with similar settings as in (A). (C) Phase shift in the parameter space of τ_rec and τ_fac. Each inner rectangle represents a PC phase shift spectrum changing over different modulation frequencies (0-30 Hz).
