Despite the well-established theoretical and experimental foundations of dopamine-driven reinforcement learning, how the reward prediction error (RPE) teaching signal modifies specific cortical memory networks remains unclear. Neural oscillations are crucial for the temporal binding of activities across distributed cell ensembles. Here, we identify that lateral entorhinal cortex layer 5 (LEC 5 ) mediated intercortical γ-synchrony is a neural correlate of the RPE signal derived from dopamine neurons in the ventral tegmental area (VTA DA ). The VTA DA -LEC 5 circuit-based intercortical γ-synchrony facilitates both learning and memory retention, and at the single-cell level, entrains the activity of cortical latent Engrams. Human brain recordings also demonstrate a universal role of γ-synchrony in the processing of prediction errors. These findings suggest that LEC 5 -mediated intercortical γ-synchrony serves as the nexus connecting reinforcement learning with the formation of cortical memory networks.
