Rodent recall: false but happy memories implanted in sleeping mice

Researchers at CRNS in Paris create artificial positive feelings in mouse's memory for first time during sleep, highlighting possible new treatment for depression

Scientists have succeeded in creating false but happy memories in mice, in the first demonstration of memory manipulation during sleep.

In the study, positive feelings about a particular place were artificially written into the animal's memory, which caused them to seek out that place in search of a reward when they woke up.
