Research shows how lost memories can be reactivated

Researchers have used brain imaging to show how memories can be reactivated in the brain without them reaching conscious awareness, showing that these memories persist even when we think they have been forgotten. Scientists from the University of Nottingham's School of Psychology used Magnetoencephalography (MEG) to show how our brains reactivate these memories even when we can't recall them, suggesting that the brain remembers even if we don't. The results have been published in The Journal of Neuroscience.
