Purpose: Human auditory nerve (AN) activity estimated from the amplitude of the first prominent negative peak (N1) of the compound action potential (CAP) is typically quantified using either a peak-to-peak measurement or a baseline-corrected measurement. However, the reliability of these 2 common measurement techniques has not been evaluated but is often assumed to be relatively poor ...

In contrast, most cranial components peaked over the midline, and even in cases with bi-lateral peaks, maximal midline electrode activity rarely dropped to less than 80% of the lateral peak amplitude. The most likely explanation for the more medial topography of components recorded from the skull is spatial smearing.

Lab 9: Conduction Velocity of Nerves - OpenWetWare

When you have two compound action potentials that reach the same (close if fine) peak amplitude, record the voltage. Choose a voltage slightly below the maximum. Generate one action potential at this voltage. Measure the time with the cursor from the start of the stimulus to the middle of the first peak of the biphasic response (see figure 9.4).

RMS Voltage of a Sinusoidal AC Waveform

RMS Voltage Equation. Then the RMS voltage ( VRMS) of a sinusoidal waveform is determined by multiplying the peak voltage value by 0.7071, which is the same as one divided by the square root of two ( 1/√2 ). The RMS voltage, which can also be referred to as the effective value, depends on the magnitude of the waveform and is not a function of ...

Warming also reduces the peak amplitude because the shorter duration of the Na current reduces its ability to charge the membrane close to ENa. Cooling, here to 6.3 ºC, lengthens the action potential because of the slower changes in the ionic currents and allows its amplitude to approach closer to ENa because of the relatively longer Na ...
