    Pallidal firing rate and alpha oscillations correlate with the severity of clinical symptoms in patients with dystonia

    U. Semenova, R. Medvednik, A. Tomskiy, V. Popov, A. Sedov (Moscow, Russian Federation)

    Objective: To examined how pallidal activity correlates with symptom severity across dystonic patients. Background: The internal segment of globus pallidus (GPi) is the most common…
