Neuron-Spectrum-4/EPM General Properties

At present time all the EEG systems presented on the market can provide the possibility to register and analyze long-latency evoked potentials (EP), however, it is not easy to find the device allowing to register short-latency EP, perform electroneuromyography (EMG), nerve conduction study (NCS), electroretinography (ERG), polysomnography (PSG) and heart rate variability (HRV) studies using only one unit.

Neuron-Spectrum-4/EPM is a unique device combining 21 EEG or long-latency EP channels, 4 wide-range polygraphic channels which can be used for short-latency EP, EMG/NCS or ERG registration, ECG channel, 2 direct current channels, breath channel. In base delivery set it allows to perform EEG studies, recording and analysis of multi-channel long-latency EP, study of short-latency auditory, visual, somatosensory and cognitive EP.

Due to perfect combination of channels and their advanced specifications, on condition that the device is provided with optional equipment and software, a comprehensive neurophysiological laboratory for polysomnography, electroneuromyography, electroretinography studies, video EEG monitoring, heart rate variability study can be created.

Evoked Potentials Study

Everything Required for Evoked Potentials Study is in the Base Delivery Set

During brain bioelectrical activity studying EEG technique does not always provide a doctor with all the required information. In such cases it is necessary to apply more informative techniques, first of all it is evoked potentials study.

Set of built- in stimulators, equipment and software included in the base delivery set of Neuron-Spectrum-4/EPM digital EEG system provides the possibility to register and analyze both long- and short-latency evoked potentials.

Neuron-Spectrum-LEP

Software and equipment for study of multi-channel long-latency evoked potentials using EEG channels with brain mapping:

  • flash visual EP
  • pattern visual EP
  • long-latency auditory EP
  • long-latency somatosensory EP (electro stimulating electrode should be available)
  • cognitive EP (P300, MMN, CNV)

Recording and analysis of multi-channel long-latency evoked potentials

Neuron-Spectrum-EP

Software and equipment for study of short- and long-latency evoked potentials using four wide-range polygraphic channels:

  • flash and pattern visual EP
  • short-, middle- and long-latency auditory EP
  • short- and long-latency somatosensory EP
  • cognitive EP (P300, MMN, CNV)

Recording and analysis of pattern visual evoked potentials

EEG recording mode.
 

Neuron-Spectrum Software Features

EEG Recording

Neuron-Spectrum software provides EEG recording on any digital EEG system of Neuron-Spectrum series by 8–32 channels (up to 64 digital derivations).

During the recording monopolar, bipolar or mixed montages in “10-20” and “10-10” schemes can be used. Any polygraphic channels (ECG, EMG, EOG, breath (airflow, chest and abdominal movements), breath noise (snoring), body position, limb movement, SpO2, etc.) can be included in montage.

The montage can be switched at any moment: before the recording, during the recording, in the process of EEG review and analysis after the recording.

It is possible to set different parameters for the different channels. For example, if you can not delete the trend of EEG isoline in frontal derivations, you can specify the more high values of high pass filter only for these derivations. You can change the parameters of any channel in the process of the recording.

In split-screen mode you can observe the process of the recording in one part of the screen and review the recorded EEG in the other one.

The software allows performing the functional tests which are standard for EEG checkups (photic stimulation, auditory stimulation, hyperventilation, eyes opening). Besides, you can perform other functional tests of any duration and in any sequence.

The flexible possibilities of stimulators programming are available.

You can watch the process of EEG recording both from the computer connected to the digital EEG system or computer connected to the same local network. After EEG recording termination, EEG can be reviewed in the “as recorded” mode as if it emulates the paper record.

EEG Storage

The records are stored in the database which provides the advanced possibilities of structuring and search. The records archives can be stored on CD or DVD. If necessary to review the archive record, the software will inform the user of the required disk to be installed in the disk drive. Besides, the records can be stored not only on the computer connected to the digital EEG system but also on any remote computer (file server).

The software operates with standard network database via GDT and HL7 interfaces.

EEG Printing

EEG with standard grid, derivations names, recording parameters can be printed on any computer printer. In the process of the recording you can mark EEG fragment which will be printed just after the recording termination.

EEG Analysis

The records can be analyzed with the use of the most modern techniques of mathematical analysis. Any fragment of the record or the whole record (with the division on epochs) can be processed.

As far as the digital EEG systems of Neuron-Spectrum series allow EEG recording not only in 35 Hz standard range but also in the wider frequency range, then not only standard ranges (alpha, beta, delta and theta) but also any ranges specified by the user can be analyzed at spectral analysis.

Brain Mapping. The software allows mapping of practically any parameter: EEG amplitude and spectrum power in the whole frequency range, EEG amplitude and spectrum power in the specified frequency ranges, rhythm index, etc.

Search of spikes and sharp waves is done automatically. In the result of search the software provides the list of the detected phenomena and mapping of these phenomena distribution on scalp.

The software provides the possibility of EEG coherent and cross-spectral analyses performing and coherence maps generating.

After EEG mathematical analysis the software allows creating the automatically generated EEG description in checkup report. Besides, the doctor can edit the report at her/his discretion, add any pictures and graphs. At that you can use structured comprehensive glossary which can be enlarged.

Trends Construction

Neuron-Spectrum software allows to display trends of spectrum components, EEG indexes, amplitude parameters of signals, HR, number and amplitude of epileptiphorm activity phenomena, etc. in any selected derivations.

In spite of the record duration all the trend is displayed on the one screen. At that you can switch on any doubtful record fragment from the trend window by one mouse click!

Two-monitor Operation Mode

The program supports automatically two-monitor operation mode. At that the results of EEG analysis, checkup report, images from the video cameras, trends, etc. are represented on the second monitor which allows to use the first monitor for EEG displaying completely.
