Figure 6From: Contact heat evoked potentials using simultaneous EEG and fMRI and their correlation with evoked pain Correlation between evoked potential amplitude and pain score. (a) Correlation of amplitude and pain score data for all baseline and fMRI sessions (n = 40) revealed a significant positive relationship (rs = 0.5956, p < 0.0001). (b) A significant, positive correlation (rs = 0.7697, p = 0.0063) was also seen when the baseline and fMRI data was pooled to give an overall evoked potential amplitude and VAS score for each subject (n = 10).Back to article page
