A Brain-to-Brain Interface with a Flexible Neural Probe for Mouse Turning Control by Human Mind

We proposed a brain-to-brain interface (B2BI) that enabled effective control of mouse turning behavior by human mind using an implantable, ultra-flexible neural probe. The neural probe was capable of writing in neural signals to the mouse brain, with effective electrical stimulation observed at a low current of 5 mu A. Additionally, a wireless electroencephalogram (EEG) device was developed for the remote transmission of human brain signals, which were decoded by the canonical correlation analysis (CCA) method with an accuracy rate of up to 98.6%. These results demonstrate the potential of B2BI technology to enable communication and control between humans and animals. (c) 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
