EEG Accessories-CAPS. Ag/AgCl Electrodes, Digitizer etc.

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:

BIOMEDICAL AUX SENSORS

FPSens - photoplethysmography sensor on finger

TRSens - respiration nasal thermometric sensor

GSRSens - galvanic skin resistance sensor

AXSen - 3-axis accelerometer with a choice of axes and amplification VGAsens - TTL output optical sensor for synchronization

Overview

System NeoRecCap is a set of NeoRecCap electrode cap with 10 preinstaled Ag/AgCl EEG electrodes and 8 channel wireless amplifier NB1-EEG8.

NeoRecCap is intended to record EEG, IR trigger events, 3D acceleration events to files of different formats (EDF+ 16 bit, BDF+ 24 bit, GDF 32 bit) or transmit it on-line via stream LSL (Lab Streaming Layer) for analyze by third-party software as MATLAB / EEGLAB, OpenViBE etc.

NeoRecCap can be used for education, research and development in EEG, neuro-computer interfaces (brain-computer interface, direct neural interface, brain interface), bio-feedback (BCI), neuromarketing, neurogaming, brain fitness.
