    Dopamine-dependent scaling of subthalamic gamma bursts with movement velocity in patients with Parkinson’s disease

    Roxanne Lofredi et al.
    Bradykinesia in Parkinson's disease may be associated to a dopamine-dependent recruitment failure of subthalamic activity in short bursts of gamma synchrony.

    Coordination of rapid cholinergic and dopaminergic signaling in striatum during spontaneous movement

    Mark Howe et al.
    Optical recordings reveal previously unknown neuromodulator dynamics in the striatum during animal movements that suggest a new interpretation of the underpinnings of bradykinetic movements exhibited in Parkinson's Disease patients.

    Decoding gripping force based on local field potentials recorded from subthalamic nucleus in humans

    Huiling Tan et al.
    Patterns of coordinated activity in the basal ganglia predict how much force we will use to grip objects, suggesting that individuals with paralysis may ultimately be able to use these signals to control graded responses in robotic devices.

    Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

    Preeya Khanna, Jose M Carmena
    Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.

    Defective synaptic transmission causes disease signs in a mouse model of juvenile neuronal ceroid lipofuscinosis

    Benedikt Grünewald et al.
    Impaired GABAergic and glutamatergic synaptic function and loss of interneurons in the amygdala, hippocampus, and cerebellum cause characteristic disease symptoms in a mouse model juvenile neuronal ceroid lipofuscinosis.

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

    Marc Deffains et al.
    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.

    State transitions in the substantia nigra reticulata predict the onset of motor deficits in models of progressive dopamine depletion in mice

    Amanda M Willard et al.
    The transition in basal ganglia output from the healthy to the diseased state is biphasic, stereotyped across models, and suggests key time points for delivering therapeutic interventions.

    Basal ganglia output reflects internally-specified movements

    Mario J Lintz, Gidon Felsen
    The basal ganglia may preferentially influence movements based on internal goals rather than those guided by external stimuli.

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

    Yashar Zeighami et al.
    The pattern of atrophy in Parkinson's disease is consistent with the disease spreading via intrinsic brain networks.

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

    Jan R Wessel et al.
    Action-selection under response-conflict is buttressed by an inhibitory control signal from the basal ganglia that non-selectively suppresses motor excitability.
