EEG Signal Quality of a Subcutaneous Recording System Compared to Standard Surface Electrodes

Figure 3

A comparison of power spectral densities (PSDs) for surface and subcutaneous recordings for the “eyes open” and “eyes closed” paradigms. Panels (a) and (b) compare the surface and subcutaneous recordings for the “eyes closed” and “eyes open” cases, respectively, while panels (c) and (d) compare the two states within each modality. Observe that the PSDs of surface and subcutaneous recordings are very similar in panels (a) and (b).
