The test is used with children or others who cannot complete a typical hearing screening
Your ear is made up of three parts — the outer, the middle, and the inner ear. The auditory brainstem response (ABR) test tells us how the inner ear, called the cochlea, and the brain pathways for hearing are working. You may also hear it called an auditory evoked potential (AEP).
The test is used with children or others who cannot complete a typical hearing screening. The ABR is also used if your symptoms might be due to hearing loss in the brain or in a brain pathway.
Frequently Asked Questions
Why do I need EEG?There are many different reasons why we may need to measure the electrical activity in our brains. Some of them include Clinical treatment and diagnosis of many common and debilitating brain disorders such as epilepsy, autism, Parkinson's disease, chronic pain, and depression, which have been correlated with changes in EEG activity. The ability to detect EEG activity has been combined with real-time feedback, allowing subjects to learn how to control their brain states voluntarily. This technique has been used in a variety of applications, including relaxation training and skill acquisition. EEG signals can be used to detect patterns of electrical activity linked to different thoughts or intentions.
"Electroencephalography (EEG) records electrical activity along the scalp. It measures voltage fluctuations resulting from ionic current within the neurons of the brain." In a conventional EEG, electrodes are placed along the scalp to measure this electrical activity using an electroencephalogram machine. The recorded signal is very similar to that of a baby monitor. The signal is transmitted to an electroencephalograph machine, which records the data on paper or a digital screen.
