Final answer:
The brain area that is organized such that successive areas respond to successively higher frequencies is called tonotopic.
Step-by-step explanation:
The brain area that is organized such that successive areas respond to successively higher frequencies is called tonotopic.
This organization is observed in the auditory cortex, which is responsible for processing auditory information. In the auditory cortex, different areas are specialized to respond to different frequencies of sound, with lower frequencies represented in posterior regions and higher frequencies represented in anterior regions.
For example, in the primary auditory cortex (area 41), the basilar membrane in the ear vibrates in response to sound waves of different frequencies and transmits this information to the auditory cortex. The tonotopic organization allows the brain to process and interpret different frequencies of sound.
