Why even happy memories fade: brain\'s selective storage mechanism identified
A study suggests people forget even pleasant memories not because the brain runs out of storage, but because it selectively takes in information and continuously reconstructs memories. Anatomy professor Michelle Spear at the University of Bristol said memory can differ widely between people even after the same experience. The brain does not store experiences like a computer and instead filters what to keep based on attention and emotion, then rebuilds memories during recall.
