IBVA is portable neurofeedback system, wirefree as brainwaves are sent by Bluetooth to an Apple Mac computer. Very user-friendly and non invasive for recording your EEG, the IBVA unit can even be tucked into a shirt pocket. Simply attach the 3 pre-gelled electrodes to the forehead, and secure with the blue IBVA headband. Now you can connect 2 users brainwaves simultaneously to one Mac, for 4 channels of EEG interaction useful in client / therapist and energy work.

Maximum recording time depends on your sampling frequency, and the size of your Mac's hard drive. When recording a 120 Hz sample (like the original IBVA system,) an 8 hour recording possible. When making a 480Hz sample, then 2 hours recording is possible.
