Hard-wired Memories

Professor Karim Nader explains that long-term memories are traditionally thought of as being fixed in the brain.

For as long as there is a theory of memory consolidation, people have thought that initially when we acquire new memories, they are in a very dynamic state and sensitive to disruption. But over time, memories were thought to be fixed in the brain. Once memories were fixed in the brain, they were thought to stay in the brain. And so, the current models of memory would say yes, once you have a long-term memory, then that information, wherever it is stored, is going to remain there for the rest of your life.
