Neurobiologist and lecturer of Physiology at the University of Cambridge Colin Blakemore explores the human memory in his fourth Reith lecture from his series entitled 'Mechanics of the Mind'.

In this lecture entitled 'A Child of the Moment', Professor Blakemore discusses how we create and store the memories which create our identity. He explains how scientists believe that memories consist of synthesized chemical molecules in the brain and reveals examples of how cerebral cortex damage can halt memory formation or lead to an overload.
