    Reward prediction error does not explain movement selectivity in DMS-projecting dopamine neurons

    Rachel S Lee et al.
    Despite the fundamental relationship between movement and value, they are represented in a separable manner in dopamine neurons.

    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.

    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.

    Reciprocal synapses between mushroom body and dopamine neurons form a positive feedback loop required for learning

    Isaac Cervantes-Sandoval et al.
    Structural and functional analysis of axonal-axonal reciprocal connections between dopamine neurons and Kenyon cells provides insight into the brain computations for normal associative olfactory learning.

    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.

    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.

    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.

    Sound exposure dynamically induces dopamine synthesis in cholinergic LOC efferents for feedback to auditory nerve fibers

    Jingjing Sherry Wu et al.
    Based on the animal’s recent history of sound exposure, cholinergic auditory brainstem neurons dynamically regulate dopamine synthesis for inhibitory feedback to the inner ear.

    Network oscillation rules imposed by species-specific electrical coupling

    Stefanos Stagkourakis et al.
    An unexpected species difference in electrical coupling of analogous neuroendocrine dopamine neurons in rats and mice reveals a role for gap junction connectivity as a band-pass filter for oscillation frequency in neural networks.

    eIF2α-mediated translational control regulates the persistence of cocaine-induced LTP in midbrain dopamine neurons

    Andon N Placzek et al.
    Building on previous work (Huang et al., 2016), we show that translational control by p-eIF2α is a defense mechanism that prevents persistent cocaine-induced synaptic synaptic potentiation underlying compulsive drug seeking.
