Neuro Feedback BESS Neurofeedback is a QEEG based Neurofeedback system. It uses the brain activity to provide feedback to the user. Polysomnography BESS Polysomnography systems are easy to use Multi Parameter Sleep study systems. E E G Brain Electrical Scan System – BESS, built over years of research, is a highly sophisticated EEG-ERP system that acquires, processes and analyzes bioelectrical activity within the brain. E R P Having been developed for research purposes, BESS is equipped with a user-friendly stimulus presentation package, capable of presenting stimuli in visual and auditory modality. Neuro Stimulation BESS provides a comprehensive Stimulus presentation package that automates functions related to ERP presentation from Presentation to Analysis, the first of its kind. Amplifiers EEG / ERP Amplifiers – BESS 32 (Portable), BESS xAmp (16 to 128 Channel), BESS FW 32/64 (Fibre link) and Epidome.
