Brain study reveals how long-term memories are erased University of Edinburgh

Vital clues about how the brain erases long term memories have been uncovered by researchers. The study in rats reveals how forgetting can be the result of an active deletion process rather than a failure to remember. It points towards new ways of tackling memory loss associated with conditions such as Alzheimer’s disease and other types of dementia. The findings could also help scientists to understand why some unwanted memories are so long-lasting – such as those of people suffering from post-traumatic stress disorders. Memories are maintained by chemical signalling between brain cells that relies on specialised receptors called AMPA receptors. The more AMPA receptors there are on the surface where brain cells connect, the stronger the memory. The team led by the University of Edinburgh found that the process…
