# Dopamine

New research reveals how acetylcholine modulates dopamine release to drive effortful behavior, while other studies explore the link between dopamine and addiction, suggesting pharmacokinetic factors may outweigh pharmacodynamic ones in cocaine choice.

### About Dopamine

"Spatial and temporal scales of dopamine transmission Nature Reviews Neuroscience Dopamine is often portrayed as a diffuse slow neuromodulator yet such signalling cannot explain its broad and sometimes rapid roles. Here Liu Goel and Kaeser review recent insights into dopamine release and receptors and present a new framework — the domain-overlap model — for dopamine signalling"
