SOFTWARE

EEG amplifier NeoRec 7/21 mini supports research software NeoRec and clinical software NEUROVisor.

NeoRec software

NeoRec is a PC software designed for experiment plannig and for recording EEG and other biomedical signals during scientific or medical research, include Evoked Potentials preprocessing.

Record files can be saved in different formats (EDF+ 16 bit, BDF+ 24 bit, GDF 32 bit) or transmited online via stream LSL (Lab Streaming Layer) for analyze by third party software as MATLAB / EEGLAB, OpenViBE etc.

SDK for software development for PC and mobile applications is provided by the manufacturer upon request.

NEUROVisor software

NEUROVisor is a clinical EEG software which available at PC and as mobile application.

Software NEUROVisor is a friendly one button solution, which provides standard montages and examination scenarios according to IFCN guidelines, automatic or semi-automatic examination procedure with voice prompts, automatic artifact rejection using ICA method, automatic generation of reports with manual editing capability.

Quantitative EEG presented by amplitude-frequency analysis of the main EEG rhythms, spectral analysis (charts and maps), independent component analysis.

ACCESSORIES

Wide range of EEG accessories MCScap are designed for NeoRec amplifiers. Different models of electrode caps with preinstalled Ag/AgCl sintered electrodes are covered all needs: from standard gel solution up to dry solution.

Textile caps in 12 sizes for the heads from 24 cm up to 66 cm circumference. Elastic material provides the most comfortable fit of the electrodes and the right positions without additional adjustment.

The material does not allow the gel or paste to dry out under electrodes fast. Marked holes for electrodes. Big holes for the opportunity to push the hair and prepare the skin for examination.

Reusable passive electrodes MCScap are based on high-quality Ag/AgCl sintered sensors which guarantee a high quality signal, a long-term stable electrical contact, a low noise reference electrode, a minimum electrode polarization, an excellent low frequency response.
