Bursts of 15-30 Hz oscillations following noxious laser stimulus originate in posterior cingulate cortex

Original language description

Previous EEG studies reported the presence of synchronised 15-30 Hz oscillations in vertex electrodes following innocuous somatosensory stimulation and noxious laser stimulation. The purpose of the present study was to analyse the sources of poststimulusincreases of 15-30 Hz oscillations during noxious laser stimulation of four different body regions and to compare the sources of the poststimulus synchronisation with the sources of the N2 component of laser-evoked potential (LEP). In 10 healthy subjects, moderately painful laser stimuli were applied to the dorsum of the right hand, dorsum of the right foot, right groin, and right side of the face. EEG data, recorded from 111 scalp sites, were analysed using event-related desynchronisation method and source dipole analysis. A profound amplitude increase of 15-30 Hz oscillations peaking 1-2 s after noxious laser stimulation was found during stimulation of each body part. The sources of these oscillations were located in the dorsal poste
