Purpose.
We provide a comprehensive verification of a new subcutaneous EEG recording device which promises robust and unobtrusive measurements over ultra-long time periods.
The approach is evaluated against a state-of-the-art surface EEG electrode technology.
Materials and Methods.
An electrode powered by an inductive link was subcutaneously implanted on five subjects.
Surface electrodes were placed at sites corresponding to the subcutaneous electrodes, and the EEG signals were evaluated with both quantitative (power spectral density and coherence analysis) and qualitative (blinded subjective scoring by neurophysiologists) analysis.
Results.
The power spectral density and coherence analysis were very similar during measurements of resting EEG.
The scoring by neurophysiologists showed a higher EEG quality for the implanted system for different subject states (eyes open and eyes closed).
This was most likely due to higher amplitude of the subcutaneous signals.
During periods with artifacts, such as chewing, blinking, and eye movement, the two systems performed equally well.
Conclusions.
Subcutaneous measurements of EEG with the test device showed high quality as measured by both quantitative and more subjective qualitative methods.
The signal might be superior to surface EEG in some aspects and provides a method of ultra-long term EEG recording in situations where this is required and where a small number of EEG electrodes are sufficient.
