Background:
Characteristics of vestibular evoked myogenic potentials (VEMPs) depend on stimulus conditions.
Objective:
To determine the optimal stimulus conditions for cervical and ocular VEMPs.
Methods:
Participants were 23 healthy subjects. We compared air-conducted cervical and ocular VEMPs elicited by various tone-burst conditions (frequencies 500-1,000 Hz, rise/fall times 1-2 ms, and plateau times 0-6 ms) with an intensity of 105 dB normal hearing level. Effects of simultaneous contralateral masking noise on VEMPs were also evaluated.
Results:
The largest cervical VEMP amplitudes were elicited by 500-750 Hz and 2-6 ms plateau time-tone-bursts, and the largest ocular VEMP amplitudes by 750 Hz and 2-4 ms plateau time-tone-bursts. Repeatability of the latency was better at 1 ms than at 2 ms rise/fall time in both VEMPs. In both VEMPs, masking noise reduced amplitude, and in ocular VEMP, amplitudes were significantly larger at the left ear stimulation than the right.
Conclusion:
Optimal tone-burst stimulation for both VEMPs seemed to be 500-750 Hz frequency and 1/2/1 ms rise/plateau/fall time without contralateral masking noise. Ocular VEMP amplitudes from left ear stimulation were originally larger than those from right ear stimulation.

Cable Subjected to Its Own Weight
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
Potential Energy
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...
