Three cortical areas are dedicated to processing auditory information: the primary auditory cortex, the secondary auditory cortex, and Wernicke's area. This statement is which of the following?

A. True.
B. False. Wernicke's area is not the area involved; rather, Broca's area is involved in processing auditory information.
C. False. The secondary auditory cortex is not involved.
D. False. Broca's area is also involved in processing auditory information.


ANS: A
Rationale: Three cortical areas are dedicated to processing auditory information. The primary auditory cortex is the site of conscious awareness of the intensity of sounds. An adjacent cortical area, the secondary auditory cortex, compares sounds with memories of other sounds. It then categorizes the sounds as language, music, or noise. Comprehension of spoken language occurs in yet another cortical area, called Wernicke's area.
