Auditory Brainstem Response (ABR)

ABR is a test that measures the electrical activity of the auditory nerve and brainstem in response to sounds presented to the ear. It can help identify problems with the neural pathway that carries sound from the ear to the brain. The test involves placing electrodes on the scalp and presenting sounds of different frequencies and intensities. The electrodes measure the electrical activity of the auditory nerve and brainstem in response to those sounds.
