Commun Biol
. 2021 Jul;
4(1):883.
PMID: 34272455
Substance use disorder (SUD) is a chronic neuropsychiatric condition characterized by long-lasting alterations in the neural circuitry regulating reward and motivation. Substantial work has focused on characterizing the molecular substrates ...

Exp Clin Psychopharmacol
. 2020 Jul;
29(4):319-333.
PMID: 32658535
Substance use disorder (SUD) is a behavioral disorder characterized by volitional drug consumption. Mouse models of SUD allow for the use of molecular, genetic, and circuit-level tools, providing enormous potential...

Neuropsychopharmacology
. 2020 May;
45(9):1463-1472.
PMID: 32375157
A large body of work has focused on understanding stimulus-driven behavior, sex differences in these processes, and the neural circuits underlying them. Many preclinical mouse models present rewarding or aversive...
