In awake behaving rats, cholinergic interneurons in the nucleus accumbens drive dopamine release via nicotinic receptors, boosting motivation to work.

L-DOPA administration increases information-seeking about potential losses without impacting information-seeking about potential gains, and as a result, it reduces the effect of valence on information-seeking.

Disinhibition of dopamine neurons in the midbrain drives heroin reinforcement, the initial step towards opioid addiction.

The molecular mechanisms by which midbrain dopamine neurons acquire the inhibitory neurotransmitter GABA for synaptic release are revealed.

Invasively recorded cortical beta oscillations form whole-brain structural and functional networks that are modulated by dopamine.

Midbrain dopamine neurons in rats signal discrepancies between predicted and actual rewards, regardless of whether the rewards are predicted on the basis of experience or inference.

Blocking D2 dopamine receptors increases goal-directed (“model-based”) control when alternative habitual ("model-free") actions are available, whereas blocking opioid receptors does not seem to have an effect on the arbitration between the two modes of acting.

Behavioral and in vivo imaging analysis in the fly suggests that mating-related sensory experience regulates female odor perception and expression of choice behavior through a dopamine-gated learning circuit.

Biperiden, but not amisulpride, delays auditory mismatch responses during environmental stability, suggesting a differential sensitivity of auditory statistical learning to muscarinic versus dopaminergic receptor status which could prove useful for developing tests that predict an individual's response to antipsychotic treatment.

Regulation of Cav2.3 Ca²⁺ channels by membrane-bound β2 subunit splice variants permits long-lasting channel activity even during prolonged and continuous activity in dopamine neurons, with implications for Parkinson's disease pathophysiology.
