Dopamine release (A) and Vmax (B) were compared between ad lib and fasted groups for mice fed the control diet with recordings grouped by anatomical slices from +1.54 (most rostral), +1.42, +1.34, +1.18, and +1.10 (most caudal) mm from bregma. Similarly, dopamine release (C) and Vmax (D) are shown for mice fed HF. Voltammetry recordings from both sexes were combined. Trend lines below violin plots show relative differences between means during ad lib and fasted states within rostrocaudal positions. (* denotes significance between ad lib and fasted states within rostrocaudal slice groupings) (*, p<0.05; **, p<0.01).
