A joint collaboration between French and American scientists has shown that traumatic events can be erased from the memory of rats. The experiments were performed with a drug known to act in the amygdala region of the brain where emotional memories are stored. They succeeded in repressing the memories of the trauma without altering any other memories, which is the first step in the development of a future therapy to treat those who suffer from Post-Traumatic Stress Disorder (PTSD)

French CNRS scientists in collaboration have shown that a memory of a traumatic event can be wiped out, although other, associated recollections remain intact.
