Are memories stored in DNA?

The idea that long-term memory might be stored in our brain’s DNA is being tested by Professor Geoff Faulkner, using brains affected by Alzheimer’s.

Geoff has already shown that the DNA in our brains is different to the DNA in the rest of our bodies and that it changes as we learn. He’s proposing that these changes are associated with how we store our long-term memories.

More recently, he’s linked these differences to the function of genes in the hippocampus, the part of the brain that controls memory and spatial navigation, and has been implicated in memory loss with ageing, schizophrenia and Alzheimer’s disease. Continue reading Are memories stored in DNA?

The ageing brain can repair itself

He has already reversed dementia and recovered spatial memories in mice through exercise. And in 2016 he and colleagues at The University of Queensland will begin clinical trials to see if exercise will have the same impact in people with dementia. Then he’ll look at depression.

Underpinning these projects is the idea that the brain is constantly changing; and that learning, memory, mood, and many other brain functions are in part regulated by the production of new neurons.
