It can be good news for those who are still living with their bad and worst memories. Neuroscientists at MIT invented a chemical way to make mice forget about bad memories. It can be done by deactivating a memory gene – Npas 4. When an individual experiences a new event, his or her brain encodes a reminiscence of it by varying the connections linking neurons.
When that happens, many genes activate. But one of them seems to be predominantly vital – a ‘master gene‘ for memory.
The gene is mainly active in the hippocampus, a brain structure known to be significant in forming long-term memories.
