Initial exploratory work demonstrated collaboration between rats in distant cages linked by signals from cortical microelectrode arrays implanted in their brains.
Therefore, the BBI system must provide a timely response, a high level of accuracy in terms of immediate decoding and retrieval of information, and real-time visual feedback of the ongoing rat movement.
The 2018 study, by Zhang and colleagues, describes wireless brain-brain interfaces that allow humans to mentally control the continuous movements of living rats.
The study showed that rat cyborgs can be seamlessly and successfully guided by the human mind to complete a navigation task in a complex maze.
And with this experiment, it has been demonstrated that computer-assisted BBI can enable collaboration between two brains through multidimensional information transfer and lead to future studies.
