| Mark D Humphries, Mehdi Khamassi, Kevin Gurne. Dopaminergic Control of the Exploration-Exploitation Trade-Off via the Basal Ganglia. Frontiers in neuroscience. vol 6. 2012-10-02. PMID:22347155. |
here we set out to reconcile recent evidence for dopamine's involvement in the exploration-exploitation trade-off with the existing evidence for basal ganglia control of action selection, by testing the hypothesis that tonic dopamine in the striatum, the basal ganglia's input nucleus, sets the current exploration-exploitation trade-off. |

| Sean B Ostlund, Nigel T Maidmen. Dopamine receptor blockade attenuates the general incentive motivational effects of noncontingently delivered rewards and reward-paired cues without affecting their ability to bias action selection.

although reward-paired cues are known to invigorate performance through a dopamine-dependent incentive motivational process, it is not known if dopamine also mediates the influence of rewards and reward-paired cues over action selection. |

however, because reinforcement learning models concentrate on discrete action selection and on phasic dopamine signals, they are silent as to how animals decide upon the rate of their actions, and they fail to account for the prominent effects of dopamine on response rates. |
