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 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.

Dopamine signaling is necessary for normal fear extinction learning.

Midbrain dopamine neurons use sophisticated secretory machinery to establish specialized sites for action potential-evoked release of dopamine from their cell bodies and dendrites.

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.

Dopamine neurons function as an ensemble to signal a multidimensional feature prediction error.

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

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

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

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