Mental Blocks, by Helen Phillips.

We know from Loftus that it is possible to insert memories into people’s minds. But is it possible to erase memories, or to remove traumatic associations from memories of adverse experiences?

Neuroscientists are investigating a process called “reconsolidation.” It seems that every time a memory is recalled, it is just as if a new memory is being laid down. This process can be manipulated with drugs, ECT, or even by playing Tetris during reconsolidation.

“We can reverse-engineer the brain’s time machine, hijack it or jump-start it.”
