Spotless Mind? Unwanted Memories Might Be Erasable Without Harming Other Brain Functions

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.
