Inhaltsangabe
This book describes the application of single photon emission tomography (SPET) to neuroactivation imaging in particular and neuroimaging in general. Protocols for SPET, neuroactivation and neuroimaging are described in detail and results are given and discussed on the basis of clinical material and case histories. Normal functional anatomy is correlated with data from MRI. High resolution cerebral blood flow (CBF) imaging is described with the use of SPET technology. Split dose CBF imaging is also mentioned, for activation studies in a variety of normal and diseased states which include the dementias (AIDS, Alzheimer's disease and multi-infarction dementia), cerebrovascular disease, depression, schizophrenia, obsessive compulsive disorders, movement disorders (Parkinson's disease, Gilles de la Tourette syndrome, Huntingdon's chorea, Sydenham's chorea), epilepsy and tumours. Examples of motor, frontal and visual activation studies are also given.
Reseña del editor
Recent explorations in the neurosciences have been progressing towards an understanding of the relationship between brain struc ture and brain function. Having passed through an era which may be described as one of a localisationist philosophy, in which discrete brain areas were seen to subserve only discrete functions, the perspective of brain-behaviour relationships has advanced in recent years to an appreciation that a more holistic approach is not only heuristically valid, but is also most likely to lead to future advances. The close relationship between the mind and the brain has been appreciated since the time of Hippocrates when he opined 'men ought to know that from nothing else but thence [from the brain] comes joys, delights, laughter and sports, and sorrows, griefs, despondency and lamentations ... and by this same organ we become mad and delirious and fears and terrors assail us'. In the nineteenth century, particularly in France and Germany, descrip tions of what are now recognised to be independent neurological diseases emerged following empirical clinical observations. Investi gation led to the identification in many cases of underlying struc tural abnormalities which could be linked to pathological changes.
