Emanations from Residuum Oscillations in Human Auditory System

چکیده
The human auditory system is divided into three main parts: outer, middle and inner auditory system. The auditory system is mainly responsible for hearing and balance. The Cochlea, which is present in the inner auditory system, consists of Basilar Membrane, Organ of Corti, OHC and IHC together execute the hearing mechanism. Otoacoustic Emissions are inaudible sounds which come out from the inner auditory system. These are produced due to Cochlear amplification wherein OHCs play an important role by providing electro-mechanical positive feedback. OAEs are mainly used for diagnosis of hearing sensitivity in new-born babies and adults. They are not produced for persons having hearing disabilities more than 25 -30 dB. The OAEs are classified into Spontaneous and Evoked types. The main objective of this project is to generate Transient-Evoked and SustainedFrequency OAEs by simulating a human inner auditory system model. The basic underlying principle of modeling the human inner auditory system used in this project is Hydrodyamics. Hydrodynamics is the study of motion of incompressible and compressible fluids. The incompressible fluids present inside the cochlea, Endolymph and Perilymph, are responsible for the movement of the BM.. Keyword-OHC,IHC,Baislar Membrane,OAE,Hydrodynamic model

Selective deficits in human audition: evidence from lesion studies
The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

متن کاملComparison of the extratympanic electrocochleography in human and rabbit
Electrocochleography (ECoG) records the electrophysiologic activity of the most peripheral part of the auditory system, the inner ear cochlea and the 8th nerve. Auditory evoked potentials being recorded are Cochlear Microphonic (CM) and Summating Potential (AP). In order to provide the proper background for laboratory research and introducing an ECoG curve of a model animal, it was decided to...
متن کاملInterindividual variation in the attractiveness of human odours to the malaria mosquito Anopheles gambiae s. s.
Differences between human individuals in their attractiveness to female mosquitoes have been reported repeatedly, but the underlying mechanisms are not well understood. Skin emanations from 27 human individuals, collected on glass marbles, were tested against ammonia in a dual-choice olfactometer to establish their degrees of attractiveness to anthropophilic Anopheles gambiae s.s. Giles (Dipter...
متن کاملEvoked oscillations in the thalamo-cortical auditory system are present in anesthetized but not in unanesthetized rats.
Over the last decade, a large number of studies have characterized stimulus-evoked oscillations in the visual cortex of anesthetized and unanesthetized animals. Comparatively, only a few studies have been performed in auditory cortex. This study compared the tone-evoked oscillations detected from the same recording sites in the thalamo-cortical auditory system of unanesthetized and anesthetized...
