Prediction error in dopamine neurons during associative learning Here, I revisit this critical issue and review new experimental evidences that tighten the link between dopamine activity and RPE First, I introduce the recent observation of a gradual backward shift of dopamine activity that had eluded researchers for over a decade
Reward prediction error in learning-related behaviors - Frontiers In this review, we first narrate the concept of reward prediction error to better understand the learning process, and discussed the dopamine signaling in the encoding of reward prediction error in detail
Post-learning replay of hippocampal-striatal activity is biased by . . . Here, we trained adult male rats on a novel maze-based reinforcement learning task designed to dissociate reward outcomes from reward-prediction errors Four variations of a reinforcement learning model were fitted to the rats’ behaviour over multiple days
Spatial localization of hippocampal replay requires dopamine . . . - bioRxiv Indeed, VTA dopamine neurons 573 are activated when SWR and replay occur during a spatial working memory task, but 574 not during subsequent sleep (Gomperts et al , 2015), indicating close coordination 575 specifically during reward learning
Building and breaking the chain: A model of reward prediction error . . . Here, we review the roles of midbrain dopamine, the locus coeruleus, and the hippocampus in event cognition to propose and simulate the theoretical influence of two prediction error signals in integrating versus segmenting events in memory
Explaining dopamine through prediction errors and beyond The most influential account of phasic dopamine holds that it reports reward prediction errors (RPEs) The RPE-based interpretation of dopamine signaling is, in its original form,
