Patient’s auditory brainstem responses to clicks

The patient’s auditory brainstem responses to clicks taken 4 years after the second hemorrhage. This was unchanged from a similar study done 4 years previously. The average responses to 3 sets of left-sided clicks were normal (in blue at bottom of panel) whereas the responses to 3 sets of right-sided clicks were abnormal (in magenta at top of panel) because the wave IV response is of small amplitude and wave V is not clearly present.
