Top: mean changes in peak dLight1.3b fluorescence (DA release) from a single representative fiber aligned to unpredicted water reward consumption at different time points up to 12 weeks post-array implantation. Shaded regions, SEM. Bottom: median peak reward ΔF/F across fibers (n = 44 fibers) in one mouse, normalized to initial responses on week 5. Upper and lower error bars are the 75th and 25th percentiles, respectively. See also Figures S1 and S2.
