Whilst the incidence of memory and awareness in anaesthesia appears not to be on the increase, the phenomenon is receiving growing attention from patients, anaesthetists, researchers and, of course, the media. This volume brings together recent advances in the wide-ranging area of research into this multi-faceted phenomenon. It is divided into four sections: monitoring depth of anaesthesia, learning and memory in anaesthesia, clinical measurement and brain function during anaesthesia, and awareness and psychological consequences of awareness during anaesthesia.
