The data reflect extracellular levels of ACh (±SEM) in the NAcc of adolescent (control n=6 and nicotine-treated n=7), adult (control n=6 and nicotine-treated n=6) and pre-exposed adult rats control n=4 and nicotine-treated n=8). Each point reflects a 10-min sampling period following saline administration and then administration of 2 doses of mecamylamine (1.5 and 3.0 mg/kg) to precipitate withdrawal (shaded areas). Asterisks (*) denote a significant difference from respective controls (p<0.05).
