The digital systems Neuron-Spectrum-4 are intended for use as digital neurophysiological systems intended for recording, processing and display biopotential signals such as Electroencephalography (EEG) and long-latency Evoked Potential (EP). Polysomnography (PSG) derives from Electroencephalography (EEG) by the means of a dedicated software module and dedicated electrodes.The devices are portable and can register up to 21 EEG channels, 1 polygraphic channel and 1 breath channel.The devices do not provide alarms, do not provide automated event marking and do not provide to the user any diagnostic conclusion about the patient's condition. They are intended for use in the patient care institutions, diagnostics centers, neurosurgical hospitals experimental laboratories and sleep laboratories. The patient group includes all ages and sexes.
A line-powered device used to record the variations of the electrical potential caused by the electrical activity of the brain, usually detected at the patient's scalp. Leads affixed to the scalp and ear lobes transmit the electric signals to the recorder, which in turn reproduces their characteristics in an electroencephalogram (EEG). They are used to study a variety of neurological conditions, evaluate psychiatric disorders and assist in localizing tumours or lesions on or near the surface of the brain.
