Summary of learning and maintenance data in dopamine-like neurons. (A) Cue evoked dopamine-like neuronal responses develop similarly in adult and adolescent animals, (B) pre-reward delivery delay period dopamine-like neuronal responses are larger in adults, and (C) reward evoked dopamine-like neuronal responses are larger in adults. All data are displayed as the mean ± SE normalized and smoothed firing rates from both age groups in all learning and maintenance sessions. Cue-evoked response time window was immediately following the cue (0 – 0.25 sec, A), pre-reward delivery window was prior to the reward (−0.55 – −0.05 sec, B), and reward evoked response window was immediately following reward delivery (0 – 0.75 sec, C). All statistical tests were performed on sessions 3–6 (underlined).
