However, he said the result had initially been a surprising one to the team of researchers.
"We didn't actually envision that this would have the effect it has," he said.
"I still remember I was doing some data analysis on Thursday night and said 'this can't be right' — and it was."
Dr Hatch said they had been continuing on the same thread as last year's research, where the team had discovered ultrasounds could be used to reverse Alzheimer's in mice.
The team of researchers had expected to confirm the therapy would not damage a healthy brain, which they did.
But then realised they had found something else — a way to slow down the brains ageing process.
"What we found is that by applying the ultrasound to these mice you could slow down or stop the change in the structure of these cells as the animals age."to continue reading this article and to hear the associated audio file, take the source link.
