Hearing, Concussion, and Sound Processing in the Brain

---

1.  Which of the following is an advantage of measuring auditory processing neurophysiologically with the FFR? It does not rely on precision of neural timing It requires only light sedation It is non-invasive It is unaffected by learning and experience

2.  Which of the following hearing functions does not typically show disruption following a concussion? Otoacoustic emissions Speech-in-noise recognition FFRs All of the above show disruption following a concussion

3.  What is meant by “distributed, integrated auditory system”? The auditory system has one long, top-down pathway that originates in the executive system and terminates at the primary afferents, but without ascending connections. The auditory system has one long, bottom-up pathway that originates at the primary afferents and terminates in the executive system, but without descending connections. The nuclei of the auditory system are highly interconnected by both bottom-up and top-down projections and are linked to other systems, including the executive system. None of the above

4.  Which of the following would NOT be an appropriate recommendation for a child diagnosed with a concussion? Abstain from school and sit at home in a quiet room Go to school and temporarily request preferential seating, such as a desk at the front of the classroom. Go to school and inform the teacher they may have to repeat instructions one-on-one for the student. All of the above

5.  Which of the following are possible symptoms of concussion? Nausea Changes to sleep patterns Anxiety All of the above
