Figure 4

Potentials evocated by the auditory oddball paradigm in two age-matched subjects: a normal one (on the top) and a cirrhotic patient with minimal HE (on the bottom). The lines marked with flags represent the response elicited by the deviant (target and rare) stimuli, the other ones the responses elicited by the frequent stimuli. The peak of P300 in the normal subject is about 300 ms from the onset (three squares of 100 ms), in the patient with minimal HE the peak of P300 is about 480 ms. Personal observations obtained by a Micromed EEG equipment—Mogliano Veneto, Italy).
