System NeoRec cap 21 BASE is the 21-channel model of the NeoRec cap DC mobile EEG (hereinafter NeoRec cap), including an EEG amplifier NeoRec 21 and the MCScap BASE for NeoRec 21 electrode cap.
NeoRec cap DC mobile EEG – is a mobile electroencephalograph for non-invasive recording of electrical activity of the brain.
NeoRec cap intended for use both in a specially equipped room and outside, including on the street. But it is necessary to exclude the influence of strong electromagnetic interference on the device during operation.
NeoRec cap 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.
NeoRec cap intended to record EEG and 3D acceleration events to files of different formats (EDF+ 16 bit, BDF+ 24 bit, GDF 32 bit) or transmit it online via stream LSL (Lab Streaming Layer) for analyze by third-party software as MATLAB / EEGLAB, OpenViBE etc.
For developers of their own software, interaction via API is provided (https://github.com/mcsltd/NB2CppDemo).
NeoRec 21 is a 21‑channel wireless EEG amplifier with a built-in accelerometer. The amplifier is designed for recording EEG with data transmission to a PC via Bluetooth in real time or recording data to a built-in SD‑card in offline mode. The amplifier is powered by a built-in battery.
Electrode cap MCScap BASE for NeoRec 21 is the textile cap with pre-installed Ag/AgCl sintered MCScap‑E electrodes with common connector for NeoRec 21 amplifier. The electrode cap is designed for non-invasive registration EEG when used with the EEG amplifier. The electrode cap is a reusable device.
