Cortical and Hippocampal Correlates of Deliberation during Model-Based Decisions for Rewards in Humans

Figure 6

BOLD signal during choices and outcomes.

During deliberation periods after choice options were presented, we observed activity in a. posterior cingulate (−2, −18, 32), anterior mPFC (4, 64, −2) and b. left hippocampus (peak −24, −10, −18), all significantly correlated with choice difficulty in the slow process. c. BOLD signal at outcome. A cluster in the nucleus accumbens (peak 10, 12, −2) correlated with reward prediction error as computed using the expectations derived from the slow process. All activations displayed at , uncorrected.
