What is the auditory reaction of the brain stem?
The brain strain, located at the intersection of the spinal cord and brain, is a vital part of the nervous system. It contains important nerve structures that are responsible for many body functions such as breathing, swallowing, balance and hearing. The auditory response of the brain stem (ABR) is an electrical signal induced from the brain stem in response to noise.
The auditory stem test (Abrt), also known as the test of the sound evoked brain stem, is a neurological test used to measure electrical signals that are induced by the brain system because it responds to sound. It is a test used to evaluate auditory and brain function. The reaction of the auditory brain stem is measured in infants and young children to test hearing problems. It is also measured when a person shows signs of hearing disorders, brain tumor, balance disorder or conditions that attack nerves such as multiple sclerosis. Because it is involuntary, the auditory reaction is also used to test neurological integrityAnd hearing for those who are in a coma do not respond or who had a stroke. The test is relatively simple-generally lasts less than 30 minutes-and is non-invasive and painless. The reaction of the auditory brain stem is measured by connecting the electrodes to the lobes of the ears and the scalp.
During the test, a series of clicks on headphones that stimulate auditory nerves and brain is supplied to the ear. Brainst gives waves or auditory potentials of the brain (BAEP) in response to clicks and which are scanned by electrodes. Then the BAEP charts and any changes that occur.
Based on the maximum and minimum of the graph and their timing in relation to the auditory stimuli, the audiologist can assess the Tzdraví nerves of hearing and any other neurological components that help in hearing. The normal range for the auditory brain stem response will vary from patient to patient and with a test device. An audiologist that inLet's take into account when evaluating the results. If the audiologist finds that the results are abnormal, other tests of the doctor may be needed.
