STD and axonal DA release exhibit a similar calcium dependency. (a) Protocol used for FSCV recordings. (b) Schematic representation of a striatal slice and average of [DA]o peaks obtained with single or pulse-train stimulations at 0, 0.5 and 2.4 mM of extracellular calcium in the aCSF, with or without the addition of 5 µM of nomifensine/sulpiride. (c) Schematic representation of a VTA slice and average [DA]o peaks obtained with pulse-train stimulations at 0, 0.5 and 2.4 mM of extracellular calcium in the aCSF containing 5 µM of nomifensine/sulpiride. (d) Average [DA]o peaks normalized to 2.4 mM of calcium obtained in the VTA and dorsal striatum (dStr) with pulse-train stimulation and aCSF containing nomifensine/sulpiride. Representative traces and voltammograms are shown on the right. Error bars represent ± s.e.m. The statistical analysis was carried out by a one-way ANOVA followed by a Dunnett test (ns, non-significant; ***p < 0.001; #p < 0.0001).
