Effects of chronic ethanol vapor and withdrawal on exogenous GABA and glutamate concentration and sensitivity to acute ethanol in lateral amygdala/basolateral amygdala. A, Representative microdialysis probe (0.5 mm). Scale bar, 1 mm. B, Histologic verification of probe site. Dashed lines indicate LA/BLA. Scale bar, 1 mm. C, Baseline dialysate concentrations of GABA (nm, left) and percent change in GABAergic transmission over time and following reverse dialysis of ehthanol (1 M, shaded area; right) in the LA/BLA of AIR and CIE-WD mice (n = 4–7). D, Baseline dialysate concentrations of glutamate (nm, left) and percent change in glutamatergic transmission over time and following reverse dialysis of ehthanol (1 M, shaded area; right) in the LA/BLA of AIR and CIE-WD mice (n = 4–7).
