Cortical gamma oscillations in isolated dystonia

We describe a novel electrophysiologic signal from the motor cortex of patients with generalized dystonia - a discrete gamma-band oscillation induced by movement and associated with emergence of dystonia. This was observed using both invasive and non-invasive methods. This phenomenon is similar to t...

Description
Summary:We describe a novel electrophysiologic signal from the motor cortex of patients with generalized dystonia - a discrete gamma-band oscillation induced by movement and associated with emergence of dystonia. This was observed using both invasive and non-invasive methods. This phenomenon is similar to the gamma oscillation reported in parkinsonian dyskinesia. •Novel electrophysiologic signal found in the motor cortex of patients with generalized dystonia.•Discrete gamma-band oscillation induced by movement and associated with emergence of dystonia.•Phenomenon similar to the gamma oscillation reported in parkinsonian dyskinesia.
