    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.

    Amygdala-ventral striatum circuit activation decreases long-term fear

    Susana S Correia et al.
    Behavior- or optogenetic-driven activation of a basolateral amygdala projection to the nucleus accumbens enhances infralimbic cortex activity and long-term fear extinction.

    1. Neuroscience

    Dopamine neuron glutamate cotransmission evokes a delayed excitation in lateral dorsal striatal cholinergic interneurons

    Nao Chuhma et al.
    Dopamine neurons make novel glutamatergic connections to striatal cholinergic interneurons in the lateral dorsal striatum that are mediated by metabotropic glutamate receptors coupled to TrpC channels.

    Common resting brain dynamics indicate a possible mechanism underlying zolpidem response in severe brain injury

    Shawniqua T Williams et al.
    The therapeutic effects of the sleeping pill zolpidem in patients with disorders of consciousness may be due to recruitment of brain cells idling in abnormally low-frequency brain waves.

    A human subcortical network underlying social avoidance revealed by risky economic choices

    Johannes Schultz et al.
    The subjective value of engaging in human social situations, and amygdala and nucleus accumbens activation and their connectivity during social decision-making, vary with social anxiety traits.

    Mesolimbic confidence signals guide perceptual learning in the absence of external feedback

    Matthias Guggenmos et al.
    Neural confidence signals can take the role of reward signals and explain perceptual learning without external feedback as a form of internal reinforcement learning.

    Striatal adenosine A2A receptor neurons control active-period sleep via parvalbumin neurons in external globus pallidus

    Xiang-Shan Yuan et al.
    Rostral and central striatum controls slow-wave sleep during active phase in mice.
    1. Neuroscience

    An open cortico-basal ganglia loop allows limbic control over motor output via the nigrothalamic pathway

    Sho Aoki et al.
    A novel connection from ventral striatum to motor cortex enables emotion and motivation to influence action and motor control.
    1. Neuroscience

    The control of tonic pain by active relief learning

    Suyi Zhang et al.
    The brain has a central cortico-striatal learning circuit that suppresses ongoing pain after injury when actively learning about things that could remove the cause of the pain.
