Recovery of synaptic responses between two stimuli (S1, S2) in control and in baclofen.A, Stimulus protocol (top) and single-sweep exemplars in baclofen. B, Averages across cells. Little change in short-term depression in control (solidsquares) is seen during the time intervals examined (20–420 msec). In baclofen (opencircles), there was additional facilitation at short intervals, which decayed exponentially (dashedline) with a 96 msec time constant (95% confidence interval, 65–180 msec). Statistical significance levels:p < 0.005 (**) and p < 0.01 (*). The eight cells contributing to the average recovery data are different from those used in Figure 1.
