Document Summary

Principle of brainstem auditory evoked response far field responses (<25ms): brain stem auditory evoked response, 5 waves. Anything wrong in the conduction pathway will affect near responses. Brain-stem auditory evoked responses initial 2 waves: auditory nerve, far field. N1, n2 = 1st 2nd negative waves. Note: the polarity may vary with reference to the electrode position. Latency and amplitude of the peaks are important. P300 a marker for schizophrenia and bipolar disorder. P300 latencies: patients>relatives>control, takes a longer time then it shouls, latency prolonged and amplitude are reduced. A similar trend has been even more consistently reported in schizophrenia literature. N170, n250, p300-600 shown picture of a face, no matter whose face it is you will see n170 if face belongs to face you"re familiar with n170 and n250. Name of face, depending on how familiar you are p300-600, simpler more. P300, complex p600, probably will also get the responses at n170 and n250.
