Abstract

In this letter, we demonstrate the use of very high performance, ultrahigh impedance, electric potential probes in the detection of electrical activity in the brain. We show that these sensors, requiring no electrical or physical contact with the body, can be used to monitor the human electroencephalogram (EEG) revealing, as examples, the a and ß rhythms and the a blocking phenomenon. We suggest that the advantages offered by these sensors compared with the currently used contact (Ag/AgCl) electrodes may act to stimulate new developments in multichannel EEG monitoring and in real-time electrical imaging of the brain. © 2002 American Institute of Physics.

Additional Information: This paper describes the remote monitoring of human brain waves. The paper represents a paradigm shift in detection of the human electroencephalogram. The ability to detect the EEG remotely, without electrical contact to the body and the identification of the alpha blocking phenomenon under these conditions is innovative work.
