Cerebral Monitoring in the Operating Room and the Intensive Care Unit: An Introductory for the Clinician and a Guide for the Novice Wanting to Open a Window to the Brain
Enno Freye; Joseph V. Levy
An evoked potential differs from the EEG mainly in two ways:
1. The EEG is a random, continuous signal, which arises from the ongoing activity of the outer layers of the cortex. An evoked potential is the brain’s response to a repetitive stimulus along a specific nerve pathway.
2. EEG signals range from 10–200 milliVolt (mV). Evoked potentials are smaller in amplitude (1-5-20 Volt requiring precise electrode positioning and special techniques (signal averaging) to extract the specific response from the underlying EEG ‘noise’. The technique of signal averaging, as originally described by Dawson in 1954 [69J, has been further developed in computer processing. The technique is now used by applying a stimulus repeatedly — preferably at randomized intervals — and to record the evoked response over the corresponding area of the brain, averaging out mathematically the change over the number of stimuli.
