Brain Advance Access published January 25, 2016 BRAIN 2016: Page 1 of 15 The neural dynamics of reward value and riskcoding in the human orbitofrontal cortex Yansong Li,1,2, Giovanna Vanni-Mercier,1,2 Jean Isnard,2,3 Franc¸ois Mauguie re2,3 andJean-Claude Dreher1,2 See Kringelbach (doi10.1093/awwxxx) for a scientific commentary on this article. The orbitofrontal cortex is known to carry information regarding expected reward, risk and experienced outcome. Yet, due toinherent limitations in lesion and neuroimaging methods, the neural dynamics of these computations has remained elusive inhumans. Here, taking advantage of the high temporal definition of intracranial recordings, we characterize the neurophysiologicalsignatures of the intact orbitofrontal cortex in processing information relevant for risky decisions. Local field potentials were
