AB  - Latency and amplitude figures for waveforms were picked at 
  their point of maximal deflection as seen at their electrode site of maximal 
  voltage distribution. The foregoing procedure for peak-picking was usually rather 
  simple and straightforward for the early peaks. However for the Late Positive 
  Complex (LPC) components due to their inherent but limited morphological identification 
  had to be used in order not to confuse and admix together different LPC components 
  from different subjects. Basically it is assumed that there are a maximum of 
  three components in a person’s 
  LPC which we call P3a, P300 and P3b. P3a is the earliest and P3b the latest 
  such component while P300 falls somewhere in the middle usually assumed as the 
  waveform’s center of gravity 
  where a distinct peak cannot be ascertained. The range of LPC morphological 
  variability which is seen in a general population including both healthy and 
  sick people is then considered to represent a kind of gradient of LPC degeneration 
  or deterioration and can be classified as such.
