Surgical insertion of an electronic hearing device (AUDITORY BRAIN STEM IMPLANTS) with electrodes to the cochlea nucleus in the BRAIN STEM rather than to the inner ear as in COCHLEAR IMPLANTATION.
Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.
Electrical waves in the CEREBRAL CORTEX generated by BRAIN STEM structures in response to auditory click stimuli. These are found to be abnormal in many patients with CEREBELLOPONTINE ANGLE lesions, MULTIPLE SCLEROSIS, or other DEMYELINATING DISEASES.
The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.
NEURAL PATHWAYS and connections within the CENTRAL NERVOUS SYSTEM, beginning at the hair cells of the ORGAN OF CORTI, continuing along the eighth cranial nerve, and terminating at the AUDITORY CORTEX.

Cochlear implants and brain stem implants. (1/4)

This chapter describes the development of two implantable prosthetic neurostimulators which, in the last 20 years, have revolutionised the management of severe-to-profound sensorineural deafness. We have witnessed their rapid evolution from the realms of esoteric laboratory abstraction, with many critics and little perceived clinical use, to a routine treatment which is safe, effective and, indeed, cost effective. It is one of the great triumphs of biomedical and surgical collaboration, and is without any doubt the greatest ever advance in the treatment of deafness.  (+info)

An auditory brainstem implant (ABI) is a surgically placed device that provides a sense of sound to individuals who have severe hearing loss and are unable to benefit from cochlear implants. Unlike cochlear implants, which stimulate the auditory nerve directly, ABIs stimulate the cochlear nucleus, a region in the brainstem responsible for processing sound.

During the ABI procedure, an electrode array is placed on the surface of the cochlear nucleus, and electrical signals are used to bypass damaged structures in the inner ear and auditory nerve. These signals are then transmitted to the brain, where they are interpreted as sound. The success of ABIs varies from person to person, but many individuals report improved ability to understand speech and recognize environmental sounds.

ABIs are typically recommended for people with hearing loss caused by damage to the auditory nerve or inner ear, such as those with neurofibromatosis type 2 (NF2), a genetic disorder that causes tumors to grow on the nerves responsible for hearing and balance. ABIs may also be considered for individuals who have had unsuccessful cochlear implantation due to damaged or absent auditory nerves.

An auditory brainstem implant (ABI) is a surgically placed device that provides a sense of sound to individuals who have severe hearing loss and cannot benefit from cochlear implants. Unlike cochlear implants, which stimulate the auditory nerve directly, ABIs transmit electrical signals directly to the brainstem, bypassing the inner ear entirely.

The ABI consists of a microphone, processor, and a series of electrodes that are surgically placed on the surface of the brainstem. The microphone picks up sounds from the environment, and the processor converts them into electrical signals. These signals are then sent to the electrodes, which stimulate the nearby nerve cells in the brainstem.

The brain interprets these stimuli as sound, allowing the individual to perceive some level of hearing. While ABIs do not provide the same level of hearing as cochlear implants, they can help individuals with profound hearing loss to communicate more effectively and improve their quality of life.

It's important to note that ABIs are typically reserved for individuals who have severe hearing loss due to damage to the inner ear or auditory nerve, and who are not candidates for cochlear implants. The procedure is complex and carries risks, so it is only recommended in cases where the potential benefits outweigh the risks.

The brainstem is the lower part of the brain that connects to the spinal cord. It consists of the midbrain, pons, and medulla oblongata. The brainstem controls many vital functions such as heart rate, breathing, and blood pressure. It also serves as a relay center for sensory and motor information between the cerebral cortex and the rest of the body. Additionally, several cranial nerves originate from the brainstem, including those that control eye movements, facial movements, and hearing.

Auditory brainstem evoked potentials (ABEPs or BAEPs) are medical tests that measure the electrical activity in the auditory pathway of the brain in response to sound stimulation. The test involves placing electrodes on the scalp and recording the tiny electrical signals generated by the nerve cells in the brainstem as they respond to clicks or tone bursts presented through earphones.

The resulting waveform is analyzed for latency (the time it takes for the signal to travel from the ear to the brain) and amplitude (the strength of the signal). Abnormalities in the waveform can indicate damage to the auditory nerve or brainstem, and are often used in the diagnosis of various neurological conditions such as multiple sclerosis, acoustic neuroma, and brainstem tumors.

The test is non-invasive, painless, and takes only a few minutes to perform. It provides valuable information about the functioning of the auditory pathway and can help guide treatment decisions for patients with hearing or balance disorders.

The cochlear nerve, also known as the auditory nerve, is the sensory nerve that transmits sound signals from the inner ear to the brain. It consists of two parts: the outer spiral ganglion and the inner vestibular portion. The spiral ganglion contains the cell bodies of the bipolar neurons that receive input from hair cells in the cochlea, which is the snail-shaped organ in the inner ear responsible for hearing. These neurons then send their axons to form the cochlear nerve, which travels through the internal auditory meatus and synapses with neurons in the cochlear nuclei located in the brainstem.

Damage to the cochlear nerve can result in hearing loss or deafness, depending on the severity of the injury. Common causes of cochlear nerve damage include acoustic trauma, such as exposure to loud noises, viral infections, meningitis, and tumors affecting the nerve or surrounding structures. In some cases, cochlear nerve damage may be treated with hearing aids, cochlear implants, or other assistive devices to help restore or improve hearing function.

Auditory pathways refer to the series of structures and nerves in the body that are involved in processing sound and transmitting it to the brain for interpretation. The process begins when sound waves enter the ear and cause vibrations in the eardrum, which then move the bones in the middle ear. These movements stimulate hair cells in the cochlea, a spiral-shaped structure in the inner ear, causing them to release neurotransmitters that activate auditory nerve fibers.

The auditory nerve carries these signals to the brainstem, where they are relayed through several additional structures before reaching the auditory cortex in the temporal lobe of the brain. Here, the signals are processed and interpreted as sounds, allowing us to hear and understand speech, music, and other environmental noises.

Damage or dysfunction at any point along the auditory pathway can lead to hearing loss or impairment.
