Memories are made of this.

The illusive nature of memory is discussed in this Equinox documentary. Thirty people recount their earliest memories in an experiment to find out how much most people remember before the age of three. Before the age of two, barely nothing is remembered. Caroline Rovee Collier describes her research into babies' memories and other aspects of children's memory is shown as a child's capacity for remembering grows through the years. Where are memories stored and how is it that we can often only remember things when the memory is triggered by something. James McGaugh describes how there are probably different memory systems within the brain and Silva Alcino talks about spatial memory. People with particular memory problems are shown. Kerry has had some damage to her temporal lobes and suffers from amnesia and word deficiencies. Geoffrey can not turn short term memory into his long term memory store following a viral illness. His IQ remains the same and strangely, since his illness he has become very good at playing table tennis, which requires strong motor memory skills. The programme ends with an account by Gary Lynch of his recent research into the chemicals that are involved in memory.
