This high-density array electroencephalograph study of the Portable Neuromodulation Stimulator demonstrates brain activity changes following exposure to both the high and low frequency pulse versions of the PoNS device used in the Company's traumatic brain injury clinical trials.
A recent Electroencephalograph (EEG) study32 recorded N170, a location in the bilateral occipitotemporal cortex that is sensitive to faces, and found that eyes were processed first, then other parts of the face were coded, and finally, face perception occurred after integration of this information.
Electroencephalograph (EEG) did not show epileptiform discharges, but it is not so unreasonable since there are almost 10-20% epileptic patients have normal EEG presentation.
During follow-up her electroencephalograph findings were consistent with encephalopathy showing generalized slow (delta-theta) activity (Figure 2).
Using tin electrodes that were mounted within an elastic cap (manufactured by Brain Products GmbH, Germany), 32 scalp sites were used to record an electroencephalograph. The left and right mastoids were referenced while a ground electrode was placed on the medial frontal area.
The influence of spikes on complexity measures has been previously characterised for electrocardiograph and electroencephalograph records [11,15].
