Interindividual variability and individual stability of pain- and touch-related neuronal gamma oscillations.

Brief painful laser and innocuous tactile stimuli have been associated with an increase of neuronal oscillations in the gamma range. Although it is indicated that event-related gamma oscillations may be highly variable across individuals, to date no study has systematically investigated interindividual variability and individual stability of induced gamma synchronization. Here, we addressed this question using two EEG datasets.

A novel tool for the removal of muscle artefacts from EEG: Improving data quality in the gamma frequency range.

Background: The past two decades have seen a particular focus towards high-frequency neural activity in the gamma band (>30 Hz). However, gamma band activity shares frequency range with unwanted artefacts from muscular activity.

New Method: We developed a novel approach to remove muscle artefacts from neurophysiological data.
