- W962227194 abstract "Researchers have used electroencephalography (EEG) as a window into the activities of thebrain. High temporal resolution coupled with relatively low cost compares favourably toother neuroimaging techniques such as magnetoencephalography (MEG). For many yearssilver metal electrodes have been used for non-invasive monitoring electrical activities ofthe brain. Although these electrodes provide a reliable method for recording EEG theysuffer from noise, such as offset potentials and drifts, and usability issues, e.g. skin prepa-ration and short circuiting of adjacent electrodes due to gel running. Low frequency noiseperformance is the key indicator in determining the signal to noise ratio of an EEG sensor.In order to tackle these issues a prototype Electric Potential Sensor (EPS) device based onan auto-zero operational amplifier has been developed and evaluated. The absence of 1/fnoise in these devices makes them ideal for use with signal frequencies ~10Hz or less. TheEPS is a novel active electrode electric potential sensor with ultrahigh input impedance.The active electrodes are designed to be physically and electrically robust and chemicallyand biochemically inert. They are electrically insulated (anodized) and scalable. Thesesensors are designed to be immersed in alcohol for sterilization purposes. A comprehensivestudy was undertaken to compare the results of EEG signals recorded by the EPS withdifferent commercial systems. These studies comprised measurements of both free runningEEG and Event Related Potentials. Strictly comparable signals were observed with crosscorrelations of higher than 0.9 between the EPS and other systems." @default.
