Ruptured arteriovenous malformation in the Auditory Nerve: technical case report.
Neurosurgery, 2005Co-Authors: Soichi Oya, Toru Matsui, Akio AsaiAbstract:Objective and importance Arteriovenous malformations in the cranial Nerves are very rare, and only one case has been reported in the literature. To our knowledge, this is the first case report of an arteriovenous malformation in the Auditory Nerve. Clinical presentation A 30-year-old woman presented with a subarachnoid hemorrhage resulting from rupture of an arteriovenous malformation in the Auditory Nerve. Intervention During the operation, the Auditory Nerve bundle was found to be severely damaged and a nidus was identified inside the bundle. Conclusion Although arteriovenous malformations are thought to arise in the 4th to 8th weeks of gestation, this case might indicate a more specific time of emergence based on embryogenesis of the cranial Nerves.

Classifying Auditory Nerve patterns with neural nets: a modeling study with low level signals
Simulation Practice and Theory, 1998Co-Authors: Frank Rattay, Alice Mladenka, Juliana Pontes PintoAbstract:Abstract In man, 30,000 fibers of the primary Auditory Nerve connect the receptor cells of the inner ear with the central Auditory nervous system. The acoustic information in the Auditory Nerve is binary coded: in every fiber up to 400 impulses (spikes) per second are propagated. However, the pattern is disturbed by the spontaneous activity of the nervous system, i.e. without any acoustic signal the high sensitive fibers transfer up to 160 spikes/s. This spontaneous activity seems to be of high importance for detecting low level acoustic signals. The purpose of this study is to use artificial neural network techniques in order to detect any low level Auditory information that is hidden in a simulated spiking pattern of the Auditory Nerve. Sinusoidal stimuli with a signal to noise ratio as low as 1 10 can be recognized from the simulated firing pattern of a single Auditory Nerve fiber.

Simulation of the electrically stimulated Auditory Nerve.
Artificial organs, 1997Co-Authors: Frank RattayAbstract:The electrically generated firing pattern in the fibers of the primary Auditory Nerve is simulated for a monopolar stimulating electrode. Using an analogous input speech signal, the spiking pattern produced with a single electrode has a simple structure, which unfortunately makes no use of the 2 important coding principles used by nature. By computer simulation, it is possible to obtain an approximation of the firing pattern of the Auditory Nerve fibers. Listening to the information carried by the compound action potential of the Auditory Nerve demonstrates that speech signals with dominant high-frequency components are difficult or not possible to discern. This paper presents a strategy for speech processing that seems to improve speech understanding for single-channel implant patients because neural patterns consisting of more temporal information can be generated.
