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).
Baer is even credited as having invented the light gun, the first video game peripheral, which was a forerunner of devices like the Wii Remote. Essentially, Baerâs work set the stage for the entire video game industry as we know it today. Born in Germany in 1922, Baer and his familyâwho were Jewishâescaped the Nazis in 1938 and fled to America.
