“False Memory Implanted in Mice”

If you’ve ever been frustrated by erratic memories, spare a thought for the mice involved in a study published in the journal Science. Researchers have been able to consistently create a “false memory”, making a mouse fearful of a place it has no reason to fear. The memory was implanted by shining blue light into the mouse’s brain, which triggered a carefully chosen group of neurons.
