Data and code for: Ferro, D., Cash-Padgett, T., Wang, M.Z. et al. Gaze-centered gating, reactivation, and reevaluation of economic value in orbitofrontal cortex. Nature Communications 15, 6163 (2024). Data contains eye gaze and spiking data during risky decision-making tasks. Code runs characterization of psychometric, gaze behavioral and neural encoding of economic value gaze-centered analyses of neural encoding at task-relevant epochs, including task delays for value reactivation and reevaluation.
