CREB modulates excitability of nucleus accumbens neurons

Yan Dong , Thomas Green , Daniel Saal , Helene Marie , Rachael Neve , Eric J Nestler & Robert C Malenka

Drugs of abuse cause activation of the cyclic AMP response element binding protein (CREB) in the nucleus accumbens (NAc). Expression of active CREB in rat NAc medium spiny neurons (MSNs) increased their excitability, whereas dominant-negative CREB had the opposite effect.
