Researchers find that memory storage molecule preserves complex memories
Researchers find that memory storage molecule preserves complex memories (12/26/2008)
In a discovery that may one day lead to the ability to erase debilitating painful memories and addictions from the brain, researchers at SUNY Downstate Medical Center have found that a molecule known to preserve memories – PKMzeta – specifically stores complex, high-quality memories that provide detailed information about an animal’s location, fears, and actions, but does not control the ability to process or express this information. This finding suggests that PKMzeta erasure that is designed to target specific debilitating memories could be effective against the offending memory while sparing the computational function of brain…“If further work confirms this view we can expect to one day see therapies based on PKMzeta memory erasure,” Dr. Fenton suggests. “Negative memory erasing not only could help people forget painful experiences, but might be useful in treating depression, general anxiety, phobias, post-traumatic stress, and addictions,” he adds.
