32-channel EEG system BRAINTEST PLUS

medical research EEGvideo-monitored EEGsleep EEG

Computer electroencephalograph for the brain electrical activity research with the functions of EEG-video monitoring, the research of evoked potentials and the possibility of using polygraphic channels. Computer electroencephalography devices of the BRAINTEST PLUS series allow recording, in various modifications, up to 32 EEG channels in the “10-20” and “10-10” systems synchronously with one ECG channel and two EOG channels. EEG is recorded in accordance with the examination protocol in standard mode or long-term monitoring mode (up to 48 hours of continuous recording). The quality of the electrode mounting is controlled automatically during the electrodes placement and during the entire period of EEG recording. The quality of contact will be displayed on the double colored front panel indicators. All BRAINTEST devices has a built-in photophonostimulator for routine EEG, special glasses and headphones for conducting evoked potentials.
