‘The world’s first brain-to-brain connection has given rats the power to communicate by thought alone.

Although monkeys have been able to control robots with their mind using brain-to-machine interfaces, work by Nicolelis’s team has, for the first time, demonstrated a direct interface between two brains – with the rats able to share both motor and sensory information.’ (New Scientist).
