Electroencephalographs

Definition : Encephalographs designed for recording the variations of the electric potential caused by the electrical activity of the brain, usually detected on the scalp. These recorders consist of a main unit that includes memory (e.g., strip chart, flash card), signal processors, and a cable that is connected at the distal tip through a head box (amplifying unit) to a set of electrodes. The electrodes are typically placed on a cap or net fixed on the scalp in an array of standardized positions. Intracranial electrodes are used in very specific procedures. The electrodes and leads transmit the bioelectrical signals to a recorder which is capable of storing their characteristics for later display in an amplitude versus time graph (i.e., an electroencephalogram); some recorders can also provide a spectral analysis of the signals using a dedicated firmware. Electroencephalographs (EEGs) are used to help in the diagnosis of neurological diseases (e.g., epilepsy), to assist in localizing tumors and lesions inside the cranium, and also facilitate the assessment of the status of patients (e.g., coma, brain death). Ambulatory and dedicated computerized EEG recorders intended to provide further analysis of EEG data and also from data taken from sleep disorder studies and/or to evaluate the electrical response of the brain to external stimuli (i.e., evoked potentials) are also available. EEGs are not intended for a real-time assessment of the electroencephalogram or other brain conditions.

Lexicor Medical Technology Inc

Company Type: Parent

The company's first product was the NeuroSearch-24 (NRS-24). Mr. Joffe's design lowered the cost of functional brain mapping systems. Additionally, the NRS-24 pioneered a new intended use for brain mapping devices; the NRS-24 allowed for "the precise, objective and consistent characterization of the spatio-spectral properties of the EEG." This was one of the first commercial applications of software in the field of Neurometrics, and with it the company pioneered the use of qualitative EEG mapping in the area of mental assessments. Prior to the advent of the NRS-24, EEG devices had been used primarily for neurological examinations. The new uses for EEG measurements that the NRS-24 created allowed professionals in psychology and other behavior therapy fields to integrate EEG devices into their practices.
