FIGURE 5.
GABA, glutamate, and serotonin levels in the IPN of nicotine-treated rats following antalarmin administration. The graph depicts nicotine-treated rats that did not receive antalarmin from Figures 1–3. Data include female (nicotine-treated n = 6; nicotine-treated + antalarmin n = 7) and male (nicotine-treated n = 6; nicotine-treated + antalarmin n = 6) rats. Each point reflects a 20-min sampling period during baseline and then following mecamylamine administration (shaded area). Asterisks (*) denote a significant difference from controls (p ≤ .05)
