British scientists may soon be able to develop a pill to ease or wipe away the stress of painful memories, according to a study published Tuesday.
By examining the nerve cells in the brain that are responsible for learning and remembering -- known as "mushroom spines" -- researchers from the University of Leicester , in central England, discovered that it was possible to alter what is remembered.
They identified a particular protein called lipocalin-2 that the brain produces in response to stress. In tests on mice, those genetically engineered without this protein were found to be less "outgoing" and preferred to "hide in the dark."
This may be exciting news for many people.
