It sounds like something out of a movie - but scientists have figured out a way to alter the emotions linked to your memories.
The research is still in early stages in lab mice, who don't have emotional outbursts or angry break-ups...but scientists say this study has the potential to help people suffering from things like post-traumatic stress syndrome.
Neuro-scientists at MIT have discovered the specific brain circuit that plays a critical role in linking either a positive or negative emotion with a memory.
Even better, they have found a way to reverse that response by manipulating those brain cells.
The hope is this could lead to new medications to help those suffering from post-traumatic stress.
