Abstract
Event related potentials in the central nervous system in response to peripheral nerve stimulation represent a valuable index of the mechanisms determining human somatosensory processes. They are of value in the diagnosis of lesions affecting the afferent pathways (5,10,11,16,19) or in the prediction of outcome (7,15). In previous work, the relationships between the amplitude of SEP components considered to originate in cerebral cortex and the local tissue blood flow have been established in the baboon (2). We have found and decsribed a threshold relationship, normal SEP amplitude being sustained only when flow is greater than about 18 ml/100g/min. We have extended this experimental investigation into a study of sensory evoked potential (SEP) in man in relation to the ischaemic events which may be associated with aneurysmal subarachnoid haemorrhage, and also to continuous monitoring of the electrical activity of the cortex during surgical operations.
