Reversing bad memories without using drugs

Scientists studying mice have found that they can switch the mouse’s memory from positive to negative and negative to positive.”

“We found that we can dictate the overall emotion and the direction of the memory.”

Sarah Knapton writes that

this is the first time that scientists have shown which brain circuits are responsible for positive and negative emotions, and reversed them.

Neuroscientists believe they can erase feelings of fear or anxiety attached to stressful events, in a breakthrough which could help treat depression or post-traumatic stress disorder.

Researchers at MIT, US, have discovered which brain circuits attach emotions to memories, and crucially, how to reverse the link.

The research was published in the journal Nature, and you can read more about it here.
