Figure 3.
An example figure produced by an EEG study.
Notes: (A) Grand average waveforms for each group. (B) Grand average topographic maps for each group. EEG ERP waveforms and topography plots of experimental heat pain elicited onto patients and healthy volunteers. This diagram illustrates how EEG analysis can be used to split cerebral activation of pain into separate temporal components, early/late anticipation and the peak evoked by pain. In addition, the topographic maps illustrate the reduced spatial resolution provided by EEG.
