Neurologists believe they have come a step closer to being able to erase unshakable haunting memories.

In research sounding like the plot of a sci-fi film, a group of researchers believe they have found the gene which performs the role of memory extinction.

The process, which occurs when new memories overwrite old ones, is being treated as the key to eventually being able completely to delete painful memories.

The research could lead to medical advances and the successful treatment of those suffering from Post Traumatic Stress Disorder or sufferers tormented by earlier experiences.

Scientists at Massachusetts Institute of Technology in America conducted the study.

They say that if a way can be found to amplify the activity of the gene, known as Tet1, it could change lives.

The research echoes the 2004 Jim Carrey and Kate Winslet film, Eternal Sunshine Of The Spotless Mind in which memories are wiped.

As part of their study, the researchers compared learning behaviour of mice with the Tet1 to mice who had their version of the gene inhibited, or as the scientists put it, "knocked out".

Both sets were trained to fear a certain cage by giving them a mild electric shock each time they were placed inside.
