Final answer:
The four major areas of the SI cortex are: Area 17, Areas 18 and 19, Area 22, and Area 23. Area 17 is responsible for visual processing, while Areas 18 and 19 further process visual information. Area 22 processes auditory information, and Area 23 further processes auditory information.
Step-by-step explanation:
The four major areas of the SI cortex are:
- Area 17: Also known as the primary visual cortex, this area is responsible for initial processing of visual information.
- Areas 18 and 19: These regions constitute subsequent areas of visual processing after Area 17.
- Area 22: Known as the primary auditory cortex, it processes auditory information.
- Area 23: This area further processes auditory information after it is received by Area 22.
