    PLoS ONE 4:e6507. 2009
    ..DA is thought to increase signal gain in active networks according to an inverted U dose-response curve, and these effects may depend on both tonic and phasic release of DA from midbrain ventral tegmental area (VTA) neurons...

    Proc Natl Acad Sci U S A 105:11963-8. 2008
    ..These results point to an underlying functional organization into cell assemblies in the ACC that may monitor choices, outcomes, and task contexts, thus tracking the animal's progression through "task space."..
