Abstract

In this issue of Neuron, Morrens et al. (2020) show that stimulus-evoked dopamine responses are enhanced by novelty and increase the rate at which animals acquire conditioned responses. These results provide a candidate neural mechanism for latent inhibition and illustrate a new role of dopamine signals in learning.

Keywords: associability; dopamine; learning; novelty.
