Abstract
This section concerns electrical activity during systemic hypotension in neuroanaesthesia. My task is to compare the various methods for recording such activity to warn of inadequate perfusion. Firstly we must examine the scientific basis for using the brain’s electrical activity as a monitor of cerebral ischaemia. We must define the characteristics of the relevant electrical changes and then consider what general methods of displaying them best suit different clinical or research purposes. There are two broad groups of monitoring methods: firstly those based on the spontaneous EEG and secondly those utilizing cerebral potentials evoked by specific external stimuli. Both spontaneous and evoked activites are only maintained in their normal form when there is adequate oxidative neuronal metabolism.
