Dopamine transients in the ventral striatum. A, dLight was applied to AcbShM, AcbC, or AcbShL, and rats were trained and tested in an ABA renewal procedure and for reacquisition. A representative recording trace is shown. Location of dLight1.1 expression and fiber tips in Acb with each rat represented at 25% opacity. B, Mean ± SEM active (A) and inactive (I) nosepokes from the five recording sessions. C, Mean ± SEM normalized dopamine transients ±3 s around Nosepoke+. Green bars above traces represent periods (with minimum consecutive threshold) of significant difference from 0 as defined by 95% CIs. D, Mean ± SEM normalized dopamine transients from –3 s to 3 s around Magazine+ for AcbShM, AcbC, AcbShL. Green bars above traces represent periods (with minimum consecutive threshold) of significant difference from 0 as defined by 95% CIs.
