For the first time, scientists have recreated the brain's learning process and can restore long-forgotten memories.
Scientists have developed an on-off switch in memory.
Using this brain prosthesis, they have helped rats retrieve long-forgotten memories.
The treatment could one day help people who suffer from memory loss due to dementia, stroke or brain injury.
U.S. scientists said Friday they have developed an on-off memory switch that helped laboratory rats remember a behavior that they had forgotten.
The brain prosthesis marks the first time that researchers have been able to duplicate the brain's learning process, restoring memories that test rats were drugged to forget, and could offer hope for people with dementia.
"Flip the switch on, and the rats remember. Flip it off, and the rats forget," said Theodore Berger of the University of Southern California's Viterbi School of Engineering's Department of Biomedical Engineering.
Working with scientists from North Carolina's Wake Forest University Department of Physiology and Pharmacology, Berger's team focused on the hippocampus, the section of the brain where memories are made.
