As a result of memories not being revisited, they can fade away with time in a process called D. decay theory of forgetting.
<h3>What happens to memory when it isn't revisited?</h3>
The brain keeps memory on the premise that it would be needed from time to time.
If we don't visit a memory therefore, the brain simply allows the memory to fade away. This is what happens according to the decay theory of forgetting.
