Wave form analysis of the brain stem auditory evoked potential.
The BSEPs elicited by monaural and binaural click stimuli were studied using a variety of monopolar and bipolar montages. The wave form of the evoked response was different on separate montages. Evidence is presented that there are multiple generators responsible for the evoked potential recorded. Furthermore binaural stimulation evoked activity in a generator not excited from either ear alone. A method of presentation of the data in terms of a vectogram is given and the use of this in disease illustrated. The implication of complex interactions of many generators upon the assessment of the record in patients is discussed.
