Losing your memory as you get older may be reversible, according to the latest research. Scientists believe they have identified specific neurons which, when defective, impair the ability to form medium-term memories. But by stimulating those neurons they believe the memory can be recovered. Ron Davis, chair of the Department of Neuroscience at Scripps Florida, and research association Ayako Tonoki-Yamaguchi, investigated memory and memory traces in the brains of both young and old fruit flies. Like other organisms, from mice to humans, there is a defect that occurs in memory with aging.
In the case of the fruit fly, the ability to form intermediate-term memory - which lasts a few hours - is lost due to age-related impairment of the function of certain neurons.
Professor Davis said: ‘This study shows that once the appropriate neurons are identified in people, in principle at least, one could potentially develop drugs to hit those neurons and rescue those memories affected by the aging process.
‘In addition, the biochemistry underlying memory formation in fruit flies is remarkably similar to that in humans so that everything we learn about memory formation in flies is likely applicable to human memory and the disorders of human memory.’  Continue to read: dailymail.co.uk
