Tetris and Zip Erase Memories

Computer game Tetris is being used by Dr. Emily Holmes to disrupt processes in the brain involved in laying down painful memories. This work is performed at Oxford University's Institute of Psychiatry.

Dr Todd Sacktor and his team at the State University of New York have been erasing the memory of a mild electric shock in rats with a drug called Zip.

"Anders Sandberg from the Future of Humanity Institute at Oxford University said nobody should object to efforts to help people suffering from serious psychiatric conditions like PTSD. But in the future, "we will be able to figure out which neural networks in the brain underpin certain memories, and to undermine them. That's going to cause some ethical problems," BBC News reports.
