Figure 5.
Fast-scan cyclic voltammetry indicates DA release and nicotine modulation differ in the dorsal striatum (d. striatum) and NAc shell. A, B, The DA release evoked by 20 Hz stimulus trains of differing length in the absence (open symbols, control) or presence of nicotine (0.1 μm, filled symbols) measured in the dorsal striatum (A) or the NAc shell (B). C, D, The DA release evoked by 5p at differing intraburst frequencies in the absence (open symbols, control) or presence (0.1 μm, filled symbols) of nicotine measured in the dorsal striatum (C) or the NAc shell (D). freq, Frequency.
