hippocampus

Memory is not a recording. It is a reconstruction — assembled fresh each time you recall it, from fragments stored across the cortex. Understanding how encoding, long-term potentiation, and retrieval actually work explains why memories are reliable enough to be useful and unreliable enough to be distorted.

Why does déjà vu happen? Neuroscience explains the memory mismatch, dual-processing, and temporal lobe theories behind the 'already seen' feeling.

How the brain encodes, stores, and retrieves memories: the hippocampus, long-term potentiation, sleep consolidation, forgetting, and why false memories feel real.
