Neuron-Spectrum General Properties

Digital EEG systems Neuron-Spectrum are modern high-tech electronic medical devices of high quality satisfying the most exacting requirements of wide circle of the customers starting from doctor in clinics and up to neurophysiologist-researcher.

High quality of EEG recording is achieved due to hardware and software solutions. The sampling rate of EEG signal is up to 5000 Hz per channel, A/D converter is 16 bits, at that the noise level is less than 0.3 µV.

The mathematical processing of the received data includes brain mapping, spectral, coherent, periodometrical analysis and automatic report generation. EEG is displayed on the computer screen with the resolution up to 2560×1600 pixels and is printed on the common paper. The impedance is indicated on the electronic unit front panel.

Options. Digital EEG systems Neuron-Spectrum can be supplied with the following options: polysomnography study; video monitoring; 3-D dipole localization of pathological activity sources; evoked potentials study; heart rate variability study; external unit for SpO₂ registration.

Neuron-Spectrum Features

EEG Sampling Rate is up to 5000 Hz, Noise Level is less than 0.3 µV High sampling rate of the signal allows to register high-frequency signal components without typical “deglutition” of sharp EEG components or abrupt amplitude decrease. The low noise level provides the possibility to apply the most sparing EEG filtration or do not carry out the filtration at all. It results in maximal saving of useful information in the initial signal. Any Electrode Can Be Used as a Referent One Any electrode can be used as a referent one, and the bipolar derivations can be recoded without placing any other additional referent electrodes, for example ear ones. Impedance Indication on the Front Panel Impedance indication on the front panel is a considerable reduction of time required for a patient preparation for the checkup with the preservation of high registration quality. Connector for Standard Electrode Cap Attachment If you use the electrode cap, you will not have to use the adapters or other devices, it will be enough just to attach the cap to standard connector. Touch Proof Connectors and Alligator Clips with Leads The Touch proof connectors and the alligator clips compatible with most cables and electrodes are used for the electrodes connection. Small Dimensions and Possibility to Operate in Unshielded Room Digital EEG systems of Neuron-Spectrum series can be used in any convenient room. It results in considerable decrease of costs required for preparation of working place, increase of personnel convenience of operation and patient's comfort. The small device dimensions is a mobility, small expenses for forwarding.

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.
