Simultaneous real time feedback produces an immersive sensory experience that is comprehensive, yet simple.

The innovative Triamp bioamplifier records and reports the EEG signal, the DC and slow cortical potentials, and the continuous impedance measurement of the sensors in real time. The simplicity of design functionality allows you to easily conduct multi-modality feedback and control for maximum effect. Atlantis powerful hardware and software technology provides rapid and accurate responses and autonomous real-time EEG-controlled feedback without a PC, and real time impedance monitoring not merely impedance checking. The ability to simultaneously and continuously measure the EEG signal, the DC potential, the SCP (slow-cortical potential) and the impedance of both the active and reference leads opens up opportunities for new research and clinical work.

The Atlantis is ideal for those ready to get started in this new age of neurofeedback monitoring at an economical investment. The Atlantis I is completely expandable and provides unparalleled results.
