Intracranial pressure is a linking keyword, uniting various aspects of diagnostics and treatment of hydrocephalus, head injury, subarachnoid haemorrhage, and brain ischaemia. This volume contains selected papers presented at the XIth International Symposium on Intracranial Pressure and Brain Biochemical Monitoring, held in Cambridge, UK, in July 2000. Various clinical and experimental methodologies are discussed including multiparameter brain biochemical monitoring (including brain oxygenation, microdialysis and novel imaging techniques), assessment of cerebral autoregulation, and measurement of brain compliance. This volume introduces neuroscientists not only into a world of newly-developed techniques, models, monitoring modalities but also theories and new concepts, which highlight directions for the further research and future clinical practice.
