Reactivating a bad memory with the company of a female reduces negative emotional memory in a mouse.

A team of scientists has managed to transform negative memories into positive ones by artificially activating neural circuits in the brain of mice

First, they generated bad memories associated with a place in the mice, and then the pleasant ones returned – or vice versa – without the need to return to the place in question.

The neurons that housed the memory of the place were reactivated in a different emotional context, thus modifying the association.

As the researchers point out, the work, published by the scientific journal Natureoffers the possibility of better understanding how emotional memory forms and changes.
