FLEXIBLE EEG ACQUISITION FOR CLINICS AND RESEARCHERS
NVX is the DC amplifier with 24, 32 or 48 monopolar channels for electrodes and 4 auxiliary bipolar channels for sensors NeoSens. The device is used in training systems, clinical and scientific researches as a part of computer-based research system for short-term registration of the electro-physiological signals, primarily EEG. The amount of channels and presence of auxiliary channels depends of models.
Basically NVX amplifiers is used with NeoRec application software. NeoRec is software for the acquisition of EEG and other biomedical signals during the process of scientific or medical research. The program records the signals in various file formats for further analysis and processing by third-party software.
Supported file formats: EDF+, BDF+, GDF, EEG, SM. For viewing or processing the recorded data, the following third-party programs and software packages are recommended: EDFbrowser, Polyman, SigViewer, EEGLAB, ERPLAB, OpenViBE, BioSig.
For Real-time access/control of data stream from amplifiers into Matlab/C++/Python/OpenVIBE for BCI and Neuro-Cognitive experiments, support for Open Source, Lab Steaming Layer ( https://github.com/sccn/labstreaminglayer ) is available.

EEG Accessories-CAPS. Ag/AgCl Electrodes, Digitizer etc.
MCScap is system of the textile EEG-recording cap with removable electrodes placed according to 10-20 or 10- 10 systems and set of passive Ag/AgCl electrodes for EEG registration.
The cap is made of elastic material that provides the most comfortable fit of the electrodes without additional adjustment and minimizes the number of caps for all possible head sizes. Numerous holes are intended for ventilation and electrode alignment to head.
MCScap combines the advantages of textile caps with possibility of easy reconfiguration and replacement of broken electrodes. Ag/AgCl sintered technology of sensors guaranties minimal polarization and long-term stability.
MCScap can be used in clinical practice, neurology and functional diagnostics, and also to scientific researches.
Sintered AG/AgCl Electrodes
There are 2 types of MCScap electrodes:
1. Point electrode MCScap-E:
Point Ag/AgCl sintered electrode for EEG recording with TouchProof 1.5 mm (DIN 42 802‑ST) connector, wire length 120 cm
2. Thin (cup) electrode MCScap-T : This is a new flat (D12*4) and lightweight (<1gr) EEG electrodes. Primarily the electrodes are designed for long-term registration, requiring maximum comfort and stability, such as EEG monitoring, somnografiya, biofeedback. Attaching electrodes to the head is possible with: - Conductive paste, - EEG cap MCScap-T, - Disposable adhesive rings through the ring-adapter.
