'Electrical surge in dying brain'
"Like 'fire raging through the brain', activity can surge through brain areas involved in conscious experience, furnishing all resultant perceptions with realer-than-real feelings and emotions."
Commenting on the research, Dr Jason Braithwaite, of the University of Birmingham, said the phenomenon appeared to be the brain's "last hurrah".
Dr Chris Chambers, of Cardiff University, said: "This is an interesting and well-conducted piece of research".
A study carried out on dying rats found high levels of brainwaves at the point of the animals' demise. Scientists at the University of Michigan monitored nine rats.
To confirm the findings a study would have to be carried out on humans.
