[Changes in the time of central neural conduction and of the amplitude of the potential N10 of the somatosensory evoked potentials in a model of subarachnoid hemorrhage in baboons].
On the ground of experiments on 6 baboons the authors tried to determined changes in the amplitude of the N10 somatosensory potential and the time of central neural conduction in relation to changes of the cerebral blood flow in subarachnoid haemorrhage. The following conclusions have been reached: the time of central neural conduction as well as the amplitude of the N10 cortical potential may serve as indicators of brain ischaemia after subarachnoid haemorrhage. The amplitude of the N10 potential seems to be an earlier indicator of ischaemia than the time of central neural conduction. The relationship of the changes in somatosensory evoked potentials and the brain blood flow is doubtless, but this relationship is not directly caused by changes in the cerebral blood flow.
