    Small molecule induced oligomerization, clustering and clathrin-independent endocytosis of the dopamine transporter

    Tatiana Sorkina et al.
    Dopamine transporter (DAT) interaction with furopyrimidine called AIM-100 in intact cells leads to dramatic oligomerization, nanoclustering and endocytosis of DAT by a novel mechanism coupled to the transporter molecule conformation.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    Retroactive modulation of spike timing-dependent plasticity by dopamine

    Zuzanna Brzosko et al.
    Dopamine, a reward signal in the brain, can retroactively convert hippocampal synaptic depression into potentiation, suggesting an elegant biological solution to the distal reward problem.

    Dopamine neurons drive fear extinction learning by signaling the omission of expected aversive outcomes

    Ximena I Salinas-Hern√°ndez et al.
    Dopamine signaling is necessary for normal fear extinction learning.

    Dopamine neurons projecting to medial shell of the nucleus accumbens drive heroin reinforcement

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

    A genetic link between discriminative fear coding by the lateral amygdala, dopamine, and fear generalization

    Graham L Jones et al.
    Discrimination of predictive and non-predictive fear stimuli requires plasticity in the lateral amygdala that is regulated by midbrain dopamine neurons.

    Midbrain dopamine neurons sustain inhibitory transmission using plasma membrane uptake of GABA, not synthesis

    Nicolas X Tritsch et al.
    The molecular mechanisms by which midbrain dopamine neurons acquire the inhibitory neurotransmitter GABA for synaptic release are revealed.
    1. Neuroscience

    Rat behavior and dopamine release are modulated by conspecific distress

    Nina T Lichtenberg et al.
    Rat behavior and dopamine release are preferentially modulated by subjective rather than objective evaluation of outcomes in a social setting.

    Opposite initialization to novel cues in dopamine signaling in ventral and posterior striatum in mice

    William Menegas et al.
    Dopamine novelty signals are localized in the posterior tail of the striatum along with general salience signals, while dopamine in the ventral striatum reliably encodes reward prediction error.
    1. Neuroscience

    Midbrain dopamine neurons compute inferred and cached value prediction errors in a common framework

    Brian F Sadacca et al.
    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.
