Researcher Nina Kraus demonstrates how EEG machines can measure auditory evoked potentials in the brainstem. By recording the brain's electrical response to sound, scientists can play back a waveform that represents exactly what the brain processed. This research provides insight into auditory processing disorders where the ear functions correctly but the brain fails to interpret the signal.

The health issues of radio host Rush Limbaugh are discussed, specifically his loss of hearing attributed to the overuse of OxyContin. The segment explains how his voice modulation changed when he could no longer hear himself through headphones.
