An EVestG FP (A) and its firing pattern signals (B and C) of OnBB segment for a CTL tilt of a typical control subject. A: The waveform's minimum point is called the action potential (AP) notch at time=10 msec. The time durations of 4.5 ms (4.5 – 9.0 ms) and 5.2 ms (11.0 – 16.2 ms) before and after the AP are considered the pre- and post- potential intervals respectively. This field potential fires repeatedly during EVestG testing and is modulated by vestibular input. B: The time interval signal of the FP occurences. C: The histogram of the time interval signal.
