Horizon: How Does Your Memory Work? (2008)

Brain-bendingQuietly terrifyingScience Gothic

Overview

Documentary

You might think that your memory is there to help you remember facts, such as birthdays or shopping lists. If so, you would be very wrong. The ability to travel back in time in your mind is, perhaps, your most remarkable ability, and develops over your lifespan. Horizon takes viewers on an extraordinary journey into the human memory. From the woman who is having her most traumatic memories wiped by a pill, to the man with no memory, this film reveals how these remarkable human stories are transforming our understanding of this unique human ability. The findings reveal the startling truth that everyone is little more than their own memory.

Deep Dive

Trivia, insights & behind the scenes

Trivia

John Hannah's narration was recorded in a single day; he reportedly found the material 'profoundly unsettling' and couldn't stop thinking about it for weeks.

Insight

The memory-erasure patient was part of an early propranolol study for PTSD — her case helped establish that emotional memory can be pharmacologically weakened, not eliminated.
