From: Effects of Parecoxib and Fentanyl on nociception-induced cortical activity
Group data for relative power of each EEG band recorded from the ACC. δ band power was decreased while other band powers were increased in response to nociceptive stimulation. A: Parecoxib had no effect on band power response. B: Fentanyl completely inhibited the band power response to nociceptive stimulation and naloxone reversed its effect. *P < 0.05, **P < 0.01, #P < 0.001.
