Can traumatic memories be erased?

Could veterans of war, rape victims and other people who have seen horrific crimes someday have the traumatic memories that haunt them weakened in their brains? In a new study, UCLA life scientists report a discovery that may make the reduction of such memories a reality.
 
"I think we will be able to alter memories someday to reduce the trauma from our brains," said the study's senior author, David Glanzman, a UCLA professor of integrative biology and physiology and of neurobiology.
 
The study appears in the April 27 issue of the Journal of Neuroscience, a premier neuroscience journal.
 
Glanzman, a cellular neuroscientist, and his colleagues report that they have eliminated, or at least substantially weakened, a long-term memory in both the marine snail known as Aplysia and neurons in a Petri dish. The researchers say they are gaining important insights into the cell biology of long-term memory.
