Nicotine influences dopamine (DA) release in the nucleus accumbens, a brain region associated with reward processing and addiction. This study examined nicotine’s effects on DA signaling using fast-scan cyclic voltammetry (FSCV) in anesthetized rats. Electrodes were implanted to stimulate DA release in the medial forebrain bundle and record signals in the ventral striatum. After administering saline or nicotine, DA levels were monitored in real-time, and electrode placement was later verified through histological analysis. Saline-treated rats showed minor DA fluctuations, with a peak signal detected at 50 minutes, while technical difficulties prevented complete nicotine data collection. However, previous experiments indicated significantly …
