Neuronal correlates of risky rewards. (a) Midbrain dopamine neurons in monkeys increase firing in anticipation of probabilistically delivered juice rewards (after C.D. Fiorillo et al., 2003)69. (b) Neurons in posterior cingulate cortex preferentially signal uncertain rewards in a visual gambling task. RF, receptive field target. (c) Changes in neuronal activity following a change in the identity of the uncertain target mirrored the development of preferences for that target (b,c after A.N. McCoy and M.L. Platt, 2005)75.
