This application note will measure nerve conduction velocity along the ulnar nerve of a human subject. This is a standard site for nerve conduction velocity measurement due to the relatively large size of the nerve and easy access of the forearm. Other nerves may be used, however.
Note: Nerve Conduction Velocity (NCV) measures should use a wired setup.
Wireless BioNomadix have a variable timing jitter of ±0.5 ms rms, due to digital data buffering and wireless transmission, and are not recommended for NCV applications or any other physiological measurement where equivalently small timing differences are being measured; instead, BIOPAC recommends our wide range of wired amplifiers, such as EMG100C.
The ETVision (ETV) wearable unit resembles an eyeglasses frame that can be worn by itself or over the participant’s prescription eyeglasses. It contains miniature “eye cameras” that view each eye and a “scene camera” that views the scene in front of the participant, and a microphone. An optional visor can be mounted to the front […]
BIOPAC provides software and hardware that allows research teams to study stimulus presentation data. Here are a few notable studies using BIOPAC equipment for research on stimuli’s effects using ECG and SCL data. Your Face Scares Me This study addressed the impact of individual differences in social anxiety by examining the effects of perceptual load and stimulus valence when […]
