The work is being done with a gene called Tet1. It’s thought to be the gene able to replace old memories with new ones.
The initial research took place in mice and it worked like this.
Two groups of rodents were used. One was normal and the other had their Tet1 turned off
Scientists used a cage capable of shocking the mice until they were afraid of it.
As you would imagine, they discovered that both sets of mice became afraid of the cage.
But when they turned off the shocking mechanism the normal group lost their fear while the mice with their Tet1 turned off remained afraid.
Researchers believe if they can boost the effects of Tet1 they would be able to wipe away old, painful memories.
The group hopes their work could offer help for anyone suffering from PTSD or other forms of trauma from their past.
Many warn there are more problematic uses as well and they urge caution with the research.
