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

    Ximena I Salinas-Hernández et al.
    Dopamine signaling is necessary for normal fear extinction learning.

    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.

    Oxytocin functions as a spatiotemporal filter for excitatory synaptic inputs to VTA dopamine neurons

    Lei Xiao et al.
    Oxytocin, a peptide linked to the processing of socially meaningful stimuli, modulates excitatory synaptic transmission in dopaminergic neurons of ventral tegmental area via retrograde endocannabinoid signaling, acting as a pathway-specific temporal filter for synaptic inputs.

    Whole-organism behavioral profiling reveals a role for dopamine in state-dependent motor program coupling in C. elegans

    Nathan Cermak et al.
    Simultaneous quantification of each of the main motor programs in the roundworm C. elegans yields new insights into the neural mechanisms that coordinate animal behavior.

    Risk of punishment influences discrete and coordinated encoding of reward-guided actions by prefrontal cortex and VTA neurons

    Junchol Park, Bita Moghaddam
    Risk of punishment during reward seeking behavior is associated with a functional "disconnection" of the PFC-VTA circuit due to a transient loss of VTA-driven theta oscillation.

    Associative Learning: How nitric oxide helps update memories

    Daniel JE Green, Andrew C Lin
    Some dopaminergic neurons release both dopamine and nitric oxide to increase the flexibility of olfactory memories.

    Cocaine-induced endocannabinoid signaling mediated by sigma-1 receptors and extracellular vesicle secretion

    Yoki Nakamura et al.
    Non-synaptic extracellular vesicles may be involved in the release of endogenous cannabinoids in the central nervous system thereby representing a novel mechanism to mediate their effects on synaptic transmission.

    HCN2 channels in the ventral tegmental area regulate behavioral responses to chronic stress

    Peng Zhong et al.
    HCN2 channels in the ventral tegmental area play an important role in the pathophysiology of chronic mild stress-induced behavioral deficits.
