Some people are very forgetful, while others can remember everything they have done. Scientists know a lot how our brains store and remember facts and experiences. There is little research how or why the brain forgets things. A new study looks forgetting. A team of researchers the USA studied the brain's process forgetting things. The researchers are cognitive neuroscientists. They study the brain and how it thinks and works. Their work may help people who have memory problems. It may also help those depression and dementia. The lead scientist, Marie Banich, said: "It may sound surprising that people can control what and how they forget."
Professor Banich said forgetting is important. She said it keeps the brain working smoothly. Her research found ways that people remove information their brain. She said: "We have control over the ability to remove information …our thoughts." This is important because it means we can focus more important tasks. However, although we can control what and how we forget, the act forgetting needs a lot effort. Another researcher, Sara Festini, agreed. She said: We've found that intentionally forgetting no-longer-relevant information the mind is beneficial, but it doesn't happen automatically." Researchers will now look why we forget recent events, where we left our keys.
