Years ago, neuroscientists discovered that forming a memory causes physical changes in the brain in which new synaptic connections grow between the neurons. Each time we recall a memory it gets modified when we save it. Based on this research, it was, recently, reported that psychologists have found a way to erase the emotional anxiety associated with bad memories without erasing the memories themselves. It is done by using a drug called Propanolol which changes the way a memory is saved after being accessed. Can you think of some ways in which this research can be applied? Do you think it is a good thing or a bad thing?
