Eeg/sonication-based brain-brain interfacing

EEG has been practically used to detect brain signals, which can control brain-computer interfaces (BCls) in a noninvasive way. Recently, low-intensity focused-ultrasound (LIFU) sonication has gained attention as a potent candidate for the noninvasive and spatially-accurate transcranial computer-brain interfacing (CBI). Based on the benefit of these two techniques, the convergence of both EEG-based BCI and sonication-based CBI approaches might eventually lead to the field of ‘brain-to-brain interface’ (BBI), in which two individual brains can communicate by sending signals through functionally minimized computers. Further exploration of this new conceptual technique will be needed to realize this technology and to apply it to a wide range of our mental communication.
