Reduction in presynaptic calcium influx by uncaged GABA at 24 and 32°C. A, Representative example of a caged GABA experiment performed at 24°C measuring the time course of reduction in calcium influx after photolysis of caged GABA.Inset, ΔF/F signals after the UV flash. Data points and traces are averages of three trials. B, Example of a similar experiment performed at 32°C.Inset, ΔF/F signals after the UV flash.C, Averages of 10 experiments at 24°C (filled circles) and 9 experiments at 32°C (open circles). Falling phases are fit by single-exponential decays with time constants of 1.77 sec at 24°C and 0.68 sec at 32°C. Inset, Rising phase of the reduction in calcium influx after photolysis shown on an expanded time scale. The onset was fit to a single exponential in both cases with time constants of 184 msec at 24°C and 70 msec at 32°C. Data points are given as mean ± SEM.
