Abstract
A template for placing electrodes for electroencephalography of acute-brain-injured victims is provided which modifies the number of electrode locations from that taught by the standard 10-20 System, and which has indicia that can be quickly and easily read by non-experts during emergency application; an acquisition unit is provided which provides a turn-key interface to the non-expert personnel who routinely attend acutely brain-injured victims, preventing change or modification of the electroencephalogram parameters by the field technician, while at the same time allowing extensive control over parameters by a remote expert EEG reader; and a method and system is provided using the template and acquisition unit of the present invention with one of a plurality of remote readers who are part of a network of trained EEG readers.
