Because the hippocampus is involved in memory formation, Frankland and his team wondered whether increasing neurogenesis in adult mice could help the rodents to remember. As contradictory as that initially seemed to Frankland, given the assumption that new neurons would mean more capacity for and potentially better memory, he says it now makes sense. Because the hippocampus is not where long-term memories are stored in the brain, its dynamic nature is not a flaw but a feature, Frankland says — something that evolved to aid learning.
The environment is changing constantly and, to survive, animals must adapt to new situations. Allowing fresh information to overwrite the old helps them to achieve that.
Researchers think that the human brain might operate in a similar way. Studies of people with exceptional autobiographical memories or with impaired ones seem to bear this out.
People with a condition known as highly superior autobiographical memory HSAM remember their lives in such incredible detail that they can describe the outfit that they were wearing on any particular day. Those with severely deficient autobiographical memory SDAM , however, are unable to vividly recall specific events in their lives.
As a result, they also have trouble imagining what might happen in the future. The integration of new neurons green into the hippocampus red bands degrades stored memories.

Various symptoms of these conditions — including flashbacks, obsessive thoughts, depressive rumination and difficulty controlling thoughts — have been linked to an overactive hippocampus. A better understanding of how to help people make traumatic memories less intrusive could help researchers to treat some of the most intractable cases. When Anderson and his colleagues looked at what happens when volunteers suppress unwanted memories — a process he calls motivated forgetting — they found that people who reported more traumatic experiences were particularly good at repressing specific memories 5.
Understanding the cognitive psychology that underlies that ability, as well as the mental resilience that is necessary for developing it, could help to improve treatment for PTSD. If forgetting is truly a well-regulated, innate part of the memory process, he says, it makes sense that dysregulation of that process could have negative effects.
More from Nature Outlooks. That question is yet to be answered. But more memory researchers are shifting their focus to examine how the brain forgets, as well as how it remembers. In the past decade, researchers have begun to view forgetting as an important part of a whole.
Memory, first and foremost, is there to serve an adaptive purpose. It endows us with knowledge about the world, and then updates that knowledge. This article is part of Nature Outlook: The brain , an editorially independent supplement produced with the financial support of third parties.
