(a) Synaptic efficacy and transfer rate were monitored (at 2 Hz) before and after unmuting induced by a 30 Hz presynaptic spike train of 2 s. (b) Synaptic efficacy and (c) transfer rate for n=7 pairs normalized to the maximal level reached during unmuting and averaged (mean±s.e.m.). Decay of these parameters was fitted with a dual exponential function (blue line): 
. SpanFAST and SpanFAST indicate the relative contributions of TauFAST and TauSLOW. Baseline was constrained to the mean value for the spikes preceding unmuting (broken line).
