Dopamine neuron ensembles signal the content of sensory prediction errors
Dopamine neurons respond to errors in predicting value-neutral sensory information. These data, combined with causal evidence that dopamine transients support sensory-based associative learning, suggest that the dopamine system signals a multidimensional prediction error. Yet such complexity is not evident in individual neuron or average neural activity. How then do downstream areas know what to learn in response to these signals? One possibility is that information about content is containeddoi:10.1101/723908 fatcat:smucn2gsfbgshmbljq2qrbh22u
