    A corticostriatal deficit promotes temporal distortion of automatic action in ageing

    Miriam Matamales et al.
    Acquisition of behavioral sequences in normally aged mice involves short and unusually fast patterns of action, some of which are reproduced by striatal circuitry manipulations in young mice and can be transitorily restored through action-related feedback.

    A cholinergic feedback circuit to regulate striatal population uncertainty and optimize reinforcement learning

    Nicholas T Franklin, Michael J Frank
    Computational modeling suggests that feedback between striatal cholinergic neurons and spiny neurons dynamically adjusts learning rates to optimize behavior in a variable world.

    Early dysfunction and progressive degeneration of the subthalamic nucleus in mouse models of Huntington's disease

    Jeremy F Atherton et al.
    In mouse models of Huntington's disease, the subthalamic nucleus, which suppresses movements, also exhibits impaired glutamate homeostasis, NMDA receptor-dependent mitochondrial oxidant stress, firing disruption, and 30% neuronal loss.

    Interpretive monitoring in the caudate nucleus

    Marianna Yanike, Vincent P Ferrera
    The caudate region of the brain signals the context in which sensory evidence is evaluated, helping animals to adapt their behavior to changing conditions.

    Homeostatic reinforcement learning for integrating reward collection and physiological stability

    Mehdi Keramati, Boris Gutkin
    A mathematical model built around the assumption that the desire to maintain internal homeostasis drives the behavior of animals, by affecting their learning processes, can explain many real-world behaviors, including some that might otherwise appear irrational.

    Neuromodulation of excitatory synaptogenesis in striatal development

    Yevgenia Kozorovitskiy et al.
    Protein kinase A regulates the rapid, activity-dependent genesis of excitatory synapses during striatal development.

    Learning multiple variable-speed sequences in striatum via cortical tutoring

    James M Murray, G Sean Escola
    Inspired by the sparse, sequential neural activity patterns observed in striatum, a new circuit model implements variable-speed activity, the encoding of multiple sequences, and a tutor/student relationship between cortex and striatum.

    A selective role for ventromedial subthalamic nucleus in inhibitory control

    Benjamin Pasquereau, Robert S Turner
    Single-unit activity consistent with a selective causal role in reactive stopping or switching behaviors is found only in the most ventromedial subregion of the subthalamic nucleus.

    Subthalamic nucleus gamma activity increases not only during movement but also during movement inhibition

    Petra Fischer et al.
    Sudden stopping of rhythmic movement is associated with a pronounced increase of 60-90 Hz gamma oscillations in the subthalamic nucleus, which have formerly been regarded as favouring movement.

    Endocannabinoid dynamics gate spike-timing dependent depression and potentiation

    Yihui Cui et al.
    The molecular mechanisms beyond the bidirectionality (tTLP and tLTD) of endocanabinoid spike-timing dependent synaptic plasticity have been identified.
