Audiologists are able to measure the speed and intensity of these pulses to determine if there is hearing loss or a lesion that is upsetting the flow of the sound information through the brainstem. This measurement is called a brainstem auditory evoked response (BAER).
The brainstem-the middle of the brain. The brainstem is located in front of the cerebellum. The brainstem is like the hard-drive of a computer. It is the main control panel for the body that passes messages back and forth between the brain and other parts of the body.The cerebrum, the cerebellum, and the spinal cord are all connected to the brainstem.he brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings-all the things that make us human. While the brain only weighs about 3 pounds, it is a highly complex organ made up of many parts.
