Electrophysiological characterization of three subpopulations of lateral VTA DA neurons. a Examples of AP firing patterns evoked by a 100 pA current step in Type 1–3 DA neurons. b Ih activation evoked by a − 150 pA current step in Type 1–3 DA neurons. c Quantification of F-I slope in Type 1–3 DA neurons. d Quantification of Ih amplitude in Type 1–3 DA neurons. e) Proportion of Type 1–3 neuronal subtypes in the lateral VTA DA neurons. Scale bar, 20 mV, 100 ms. Statistics, One-way ANOVA and Bonferroni post-hoc test. *, p < 0.05; **, p < 0.01; ***, p < 0.001. Numbers in parentheses reflect numbers of cells and animals, and are presented as (N = cells/N = animals). Characterization was done with SHAM operated mice
