The chip, which is part silicon and part human brain cells, has been implanted into the base of Diana Holdstock's brain. It is able to monitor the level of various chemicals in her body and pump out the drugs she needs.

Researchers at De Montfort University in Leicester believe the chip will pave the way for a neuronal supercomputer.

"The soft chip can take into account changes in Diana's daily rhythms and hormonal cycles and give her just enough painkillers to keep her comfortable
