    Emergence of visually-evoked reward expectation signals in dopamine neurons via the superior colliculus in V1 lesioned monkeys

    Norihiro Takakuwa et al.
    The subcortical visual pathway through the midbrain superior colliculus is responsible for visually evoked Pavlovian conditioning and dopamine neuron responses with predicted value in monkeys, which remained after lesioning V1.

    Tonic firing mode of midbrain dopamine neurons continuously tracks reward values changing moment-by-moment

    Yawei Wang et al.
    Although the phasic activity of midbrain dopamine neurons is known to represent reward values, these neurons displayed a tonic firing mode to continuously track reward values changing moment-by-moment.

    Gi/o protein-coupled receptors in dopamine neurons inhibit the sodium leak channel NALCN

    Fabian Philippart, Zayd M Khaliq
    The sodium leak NALCN channel functions as a core effector of GABA-B and D2 receptors that is used along with GIRK channels to regulate action potential firing in dopamine neurons.

    Dopamine receptor 1 neurons in the dorsal striatum regulate food anticipatory circadian activity rhythms in mice

    Christian M Gallardo et al.
    For mice, knowing when it is time to feed is dependent on the neurotransmitter dopamine and the D1R receptor of neurons in the dorsal striatum.
    1. Neuroscience

    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

    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.
    1. Neuroscience

    Dopamine neurons projecting to the posterior striatum form an anatomically distinct subclass

    William Menegas et al.
    Dopamine neurons projecting to different targets receive a similar set of inputs, rather than forming reciprocal connections, whereas those projecting to the posterior striatum receive a distinct set of inputs.
    1. Neuroscience

    Midbrain dopamine neurons signal aversion in a reward-context-dependent manner

    Hideyuki Matsumoto et al.
    Dopamine neurons signal value prediction errors (VPEs) integrating information about both reward and aversion, in low reward contexts, whereas VPEs in some dopamine neurons are distorted in high reward contexts.
    1. Neuroscience

    Dopamine neurons learn relative chosen value from probabilistic rewards

    Armin Lak et al.
    When learning the reward probability of novel cues, dopamine neurons convey dissociable value and novelty signals.
    1. Neuroscience

    Dopamine neuron dependent behaviors mediated by glutamate cotransmission

    Susana Mingote et al.
    The conditional reduction of glutaminase in mouse dopamine neurons selectively attenuates glutamate cotransmission at phasic frequencies, revealing the role of dopamine neuron glutamate cotransmission in the attribution of motivational salience.
