How can we explain amnesia for the past, yet retention of knowledge learned at school? Why do we begin to forget people’s names when we are in our fifties? Why do people with Alzheimer’s disease have difficulty in finding their way? ‘Remembering’ considers these questions and looks at the difference between ‘episodic’ and ‘semantic’ memories and the importance of the hippocampus region of the brain. Episodic and semantic memories depend on distinct anatomical systems: a medial system remembers events in our life, and a ventral and lateral system is for knowledge concerning objects. The effects of ageing, dementia, and Alzheimer’s disease on memory are also discussed.
