Julie is a high school softball player and in her last game, she was struck in the head by a wild pitch. She blacked out and her coach called 911. In the ambulance, Julie complained that the paramedics were yelling at her and the sirens must be broken because they seemed very noisy. She wanted to know if there was cotton she could put in her ears because everything was so loud. Where was Julie hit? What is the function of this part of the brain?
