AUDITORY NERVE ACTION POTENTIALS IN MAN

The recording of nerve action potentials through skin in man.

Electrical stimulation of peripheral nerve in man has been shown to produce cerebral responses (Dawson, 1947), and analysis of these responses has made clear the need for some means of investigating the nature of the sensory afferent volleys concerned. Experiments carried out in 1945 suggested that it was sometimes possible to record through the skin action potentials in the ulnar nerve of one ...

Modeling of Mechanoelectrical Transduction of Hair Cells to Action Potentials in the Auditory Nerve

An auditory nerve model based on Meddis model is test in this project. In this model, the input sound was decomposed into different constituent single frequencies, and was therefore responded by individual hair cells. Mechanical amplification during the transduction process was taken into account. The deflection was translated into the change in membrane potential, which was subsequently used a...

Sensory nerve action potentials in patients with peripheral nerve lesions.

In 1949 Dawson and Scott described a method of examining sensory impulses in human peripheral nerves. By their technique, the median or ulnar nerve at the level of the wrist was stimulated electrically using single shocks, and the action potential of the afferent volley recorded through surface electrodes placed over the nerve trunk at a higher level in the arm. The afferent volley contained bo...

Effects of acoustic noise on the auditory nerve compound action potentials evoked by electric pulse trains.

This study investigated the effects of acoustic noise on the auditory nerve compound action potentials in response to electric pulse trains. Subjects were adult guinea pigs, implanted with a minimally invasive electrode to preserve acoustic sensitivity. Electrically evoked compound action potentials (ECAP) were recorded from the auditory nerve trunk in response to electric pulse trains both dur...
