Abstract
The functions of the central nervous system are accurately reflected in the generation of electrical impulses. Modern electronic techniques have enabled us to record and analyse a vast number of electrical signals from the central and peripheral nervous system and to attempt a correlation of the form and consistency of these signals with a variety of disease states. For many years the principal effort in understanding the brain’s electrical signals lay in an attempt to unscramble the complexity of the electroencephalogram, and indeed immensely valuable advances in the understanding of the function of the nervous system was made by such efforts. From the neurosurgeon’s point of view, however, the greatest advance in electronic technology was the application of event related potentials, potentials which could be produced by an externally applied stimulus to a normal pathway, and the behavior of the central and peripheral nervous systems to such stimulation recurrently assessed. It is now possible to challenge the function of all the major afferent systems, somatosensory, visual, and auditory and to monitor their activity at various levels throughout the CNS. Increasing interest has now been shown in the evocation of motor activity by direct stimulation of the CNS and over the next few years we may expect increasing sophistication, both in the techniques for stimulation and of analysis which will render their application to neurosurgical circumstances both easier and more widespread.
