Custom earpiece developed to monitor seizures

MIT Technology Review : To study brain activity in patients who experience seizures, researchers use electroencephalography (EEG). Because the procedure requires connecting the patient to a machine via multiple electrodes and cables, its use is limited and practical for only short periods of time. Now Danilo Mandic of Imperial College London and colleagues have designed a small device, similar to a hearing aid, that can be worn in the ear. Using the device, doctors can monitor patients over much longer periods of time. The ear is an ideal location because it shields the device from extraneous noise and ensures that it is always placed in the same spot.
