Brainy: Scientists have installed a computer chip in a rat's brain replacing brain tissueScientists have used a computer chip to restore cognitive function in a rat's brain sparking hopes the technology could one day help humans.
The chip mimics the cerebellum, a small region of the brain which plays an important role in motor control and movement.
Scientists used it to make a laboratory rat learn a conditioned motor reflex - blinking.
The development is another step forward in a process which could one day be used in humans to repair the effects of dementia, strokes and other brain injuriesThe development is another step forward in a process which could one day be used in humans to repair the effects of dementia, strokes and other brain injuries.
It could also be used to improve healthy brain function.
Francesco Sepulveda, from the University of Essex in Colchester, told New Scientist: 'This demonstrates how far we have come towards creating circuitry that could one day replace damaged brain areas and even enhance the power of the healthy brain.'
Neuro-scientists have already developed implants so paralysed people can move prosthetic limbs or a computer cursor using their thoughts to activate machines.
However, this process is one-way; either from the device to the train or vice-versa.
Matti Mintz, from Tel Aviv University in Israel, has developed the artificial cerebellum which sits on the outside of the skull and is wired to the brain using electrodes.
