System NeoRec cap 21 mini DRY
System NeoRec cap 21 mini DRY is the 21-channel model of the NeoRec cap DC mobile EEG (hereinafter NeoRec cap), including an EEG amplifier NeoRec 21 mini and the DRY cap for NeoRec 21 mini 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 mini is a 21‑channel wireless EEG amplifier with a built-in accelerometer
Electrode cap DRY cap for NeoRec 21 mini is the textile cap with pre-installed dry passive Ag/AgCl
