The central nucleus of the IC is a nearly obligatory relay in the ascending auditory system, and most likely acts to integrate information (specifically regarding sound source localization from the superior olivary complex [13] and dorsal cochlear nucleus) before sending it to the thalamus and cortex. [1]
An ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In mammals, the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals ...
Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. [1] The academic field concerned with hearing is auditory science. Wikiversity has learning resources about Global Audiology.
The cochlear nerve (also auditory nerve or acoustic nerve) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain. The other portion of the vestibulocochlear ...
t. e. Auditory phonetics is the branch of phonetics concerned with the hearing of speech sounds and with speech perception. It thus entails the study of the relationships between speech stimuli and a listener's responses to such stimuli as mediated by mechanisms of the peripheral and central auditory systems, including certain areas of the brain.
e. The middle ear is the portion of the ear medial to the eardrum, and distal to the oval window of the cochlea (of the inner ear). The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear. The hollow space of the middle ear ...
Human auditory system. Sound localization is the process of determining the location of a sound source. The brain utilizes subtle differences in intensity, spectral, and timing cues to localize sound sources. [3][4][5] Localization can be described in terms of three-dimensional position: the azimuth or horizontal angle, the elevation or ...
The central auditory system converges inputs from both ears onto neurons within the brainstem. This system contains many subcortical nuclei that collect, integrate, and analyze afferent signals from the ears, for extraction and analysis of the dimensions of sounds. The outcome is a representation of auditory space and auditory objects. [3] [11]
