Proof it’s possible to enhance or suppress memories

Using optogenetics to stimulate different areas of the hippocampus has the ability to enhance or suppress memories in mice. The findings could have implications for suppressing memories associated with traumatic events in PTSD, and also in enhancing cognitive ability or improving memory for those with neurodegenerative diseases, in the future.
