    Movement-related coupling of human subthalamic nucleus spikes to cortical gamma

    Petra Fischer, Witold J Lipski ... R Mark Richardson
    When coupling between STN spikes and cortical gamma oscillations was strong, subsequent movement was initiated earlier, independent of changes in mean firing rates, demonstrating the importance of relative spike timing.

    Cortico-subcortical β burst dynamics underlying movement cancellation in humans

    Darcy A Diesburg, Jeremy DW Greenlee, Jan R Wessel
    Burst-like neural activity in the β-frequency band conveys inhibitory commands within long-proposed cortico-subcortical networks for motor inhibition, with inhibitory activity in STN preceding thalamic activity, which has strong implications for movement disorders marked by abnormalities in β-bursting.

    Multi-study fMRI outlooks on subcortical BOLD responses in the stop-signal paradigm

    Scott Isherwood, Sarah A Kemp ... Birte Forstmann
    A novel meta-analytical method aggregating five SST datasets does not find evidence for the innervation of the hyperdirect or indirect cortico-basal-ganglia pathways in successful response inhibition.

    Non-selective inhibition of inappropriate motor-tendencies during response-conflict by a fronto-subthalamic mechanism

    Jan R Wessel, Darcy A Waller, Jeremy DW Greenlee
    Action-selection under response-conflict is buttressed by an inhibitory control signal from the basal ganglia that non-selectively suppresses motor excitability.

    Dopamine role in learning and action inference

    Rafal Bogacz
    A mathematical model describes the function of dopaminergic neurons in both learning and action planning.

    Network structure of brain atrophy in de novo Parkinson's disease

    Yashar Zeighami, Miguel Ulla ... Alain Dagher
    The pattern of atrophy in Parkinson's disease is consistent with the disease spreading via intrinsic brain networks.
    1. Neuroscience

    Subthalamic, not striatal, activity correlates with basal ganglia downstream activity in normal and parkinsonian monkeys

    Marc Deffains, Liliya Iskhakova ... Hagai Bergman
    The spiking activity of the subthalamic nucleus, rather than the activity of striatal projection neurons, orchestrates basal ganglia downstream activity and output commands in health and Parkinson’s disease.

    Primate homologs of mouse cortico-striatal circuits

    Joshua Henk Balsters, Valerio Zerbi ... Rogier B Mars
    Connectivity fingerprint matching bridges the gap between mouse and primate neuroanatomy, addressing crucial questions surrounding brain evolution that likely impact translation across species.

    Interrogating basal ganglia circuit function in people with Parkinson’s disease and dystonia

    Srdjan Sumarac, Kiah A Spencer ... Luka Milosevic
    The hypo- versus hyperkinetic nature of Parkinson’s disease and dystonia, respectively, may be reflected by differences in disease-specific spiketrain dynamics and striato-pallidal synaptic plasticity.

    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.
