Average acetylcholine efflux (± SEM) for all groups during the first session of in vivo microdialysis (expressed as a percent of baseline). There were four baseline collections, followed by two high K⁺/Ca²⁺, and four post-stimulation collections. There were no significant differences between groups during baseline collections. There was no significant interaction between time point and treatment group, but the ET and NC groups were compared directly due to the variability in the IC group. Following the administration of a high K⁺/Ca²⁺ aCSF, ethanol-exposed animals had a smaller increase in acetylcholine, when compared to NC animals (a). Samples sizes for the NC, IC, and ET groups were 7, 6, and 3, respectively.
