Brain-to-brain communication system overview. On the left, the brain-computer interaction subsystem is shown schematically, including electrodes over the motor cortex and the EEG amplifier/transmitter wireless box in the cap. Motor imagery of the feet codes the bit value 0, of the hands codes bit value 1. On the right, the computer-brain interface system is illustrated, highlighting the role of coil orientation for encoding the two bit values. Communication between the brain-computer interaction and computer-brain interface system components is mediated by the Internet. Image credit: Grau C et al.
