Scientists have discovered more about what happens to the brain as we die.
A study on rats shows that the brain experiences a huge surge of electricity during the moment of death, suggesting that they are experiencing a higher state of consciousness.
It could explain why people claim to see white light or "life flash before their eyes" during near-death experiences.
Dr Jason Braithwaite from the University of Birmingham says that since this surge is happening in rats, it could also happen in humans.
