Characterisation of nociceptive-specific brain activity.
Average EEG activity recorded during (A) background, (B) in response to non-noxious control stimulation and (C) following noxious heel lance in 6 infants. The nociceptive-specific principal component (PC) is overlaid in red. The PC weights were significantly greater (*p < 0.05) in response to lance than background and control (D). Error bars indicate standard error of the mean.
