How Human Memory Works: The Science Explained - The Deep Talk

In 1953, a young man known publicly only by his initials, H.M., underwent brain surgery to stop severe seizures — and woke up unable to form a single new memory for the rest of his life. He could hold a conversation, then forget it had ever happened the moment he looked away. His case became one of the most cited in the history of neuroscience, because it proved something doctors had only suspected: memory isn’t stored in one place in the brain, and losing the right piece of tissue can erase your ability to build a future at all. Understanding how human memory works matters far beyond textbook curiosity. It shapes how we study, how we age, how we grieve, and how confidently we can trust our own recollection of events. As Dr. Sandeep Kaur explained on Radio Haanji’s Deep Talk Show, memory isn’t a single system but a distributed, reconstructive process spread across trillions of synapses — closer to a puzzle than a video recording. This article walks through what memory is, how it forms, why children can’t remember infancy, and what actually works to strengthen recall — grounded in both classical philosophy and modern neuroscience.
