DEVICE: Compumedics Okti (09342451002211)

An electrically-powered device designed for noninvasive recording of the electrical activity of the brain for display in the form of a graph [electroencephalogram (EEG)], typically to study a variety of neurological conditions, evaluate psychiatric disorders, and/or assist in localizing tumours or lesions on or near the surface of the brain. It is designed to acquire electrical signals from electrodes typically attached to the scalp and ear lobes. The results may be displayed via print-out or electronically; data interpretation and/or telemetry features may also be included.

A portable electrically-powered device designed for recording of electroencephalographic signals in ambulatory patients for periods usually from 24 to 72 hours to assess a variety of neurological conditions (e.g., epilepsy) and psychiatric disorders; it is not intended for inpatient monitoring. It is a small unit designed to be worn by the patient with an appropriate signal amplifier, and intended to be used with a set of scalp electrodes that are placed on the cranium of the patient. The resulting electroencephalogram (EEG) data is analysed after the recording period using an appropriate computer/software.
