    J Neurosci 29:3695-704. 2009
    ..This, in turn, was accompanied by impaired recruitment of the ventral striatum and the right lOFC during reversals, which might explain the behavioral differences between the genetic groups...

    Cognitive Neurology Research Group, Max Planck Institute for Neurological Research, D 50931 Cologne, Germany
    J Neurosci 29:7489-96. 2009
    ..Thus, both the window of trials over which reinforcement information is integrated and adjustment of action values in the RCZ covary with the stochastics of the environment...

    Neurosci Biobehav Rev 33:48-60. 2009
    ..Here, we review the evidence for neurotransmitter effects on this function in humans. In this light, we critically discuss currently debated models of performance monitoring and potential alternatives...

    ..NMDA receptors on the contrary appear to be required only for approach learning because phasic DA increases during positive PEs are NMDA dependent, whereas phasic decreases during negative PEs are not. ..

    J Neurosci 31:1606-13. 2011
    ..These findings show that dopamine-dependent mechanisms enhance reinforcement learning signals in the striatum and sharpen representations of associative values in prefrontal cortex that are used to guide reinforcement-based decisions...
