Response magnitude (as indicated by fluorescence ratio) of TG neurons from control (n = 134 cells) vs. ethanol (n = 178 cells) rats to 1% or 3% ethanol, AITC, capsaicin, or KCl. We compare fluorescence ratios (mean ± SE) across maternal diet treatments within each panel, using the unpaired t-test with Welch’s correction for unequal variances (*P ≤ 0.03, **P < 0.0001; NS, not significant).
