Cue-induced drug craving progressively increases after prolonged withdrawal from drug self-administration in laboratory animals, a behavioral phenomenon termed “incubation of drug craving.” Studies over the years have revealed several important neural mechanisms contributing to incubation of drug craving.

We then review several key publications from the past year on behavioral and mechanistic findings related to incubation of drug craving.
