Bringing the age of direct-neural interfaces closer, researchers have
created
a robot
controlled by the brain of a fish: (NewScientist)
To create the hybrid, the team extracted a lamprey's brainstem and part of
its spinal cord under total anaesthetic, and maintained it in an oxygenated
and refrigerated salt solution... Mussa-Ivaldi and his colleagues then attached
electrodes to stimulate the Müller cells with the sorts of frequencies they
would normally receive. Other electrodes monitored the activity at the axons,
the output part of the neurons.
