Pain-related oscillations
Nociceptive stimuli induce changes in the magnitude of oscillatory brain activity which is not phase locked, possible related to nociception or pain. This induced activity was found as a brief increase in gamma power in the 40-100 Hz frequency range, whose magnitude appears to correlate better with subjective pain intensity than the amplitude of phase-locked evoked potentials and could thus be a more specific marker for nociception. Besides gamma band oscillations (GBOs), nociceptive stimuli also induce changes in the magnitude of oscillations in other frequency bands, such as a suppression of alpha-band (7-13 Hz) and beta-band oscillations (13-30 Hz), a respective rebound of beta-band oscillations, and an increase in power of low-frequency delta oscillations (0-5 Hz).
