Which statement correctly describes the major cortical visual areas involved in motion, color, and form processing?

• A. V1 handles initial feature extraction; MT/V5 processes motion; V4 processes color and form.
• B. MT/V5 handles color; V4 handles motion; V1 handles language.
• C. V1 handles color; MT/V5 handles form; V4 handles motion.
• D. V1 handles audition; MT/V5 handles color; V4 handles motion.

Answer: (A)

V1 is the primary visual cortex where neurons begin the real work of vision, extracting basic features such as edges, orientations, and contrast. MT/V5 is specialized for motion perception, integrating motion signals to detect how objects move in space. V4 is the area most closely tied to color processing and also contributes to forming coherent color-based representations of objects, with some role in intermediate form features. So the statement that V1 handles initial feature extraction, MT/V5 processes motion, and V4 handles color and form lines up with what each area is known to do, making it the best description. Other options mix up these roles (for example, assigning color to MT/V5, motion to V4, or language and audition to V1), which does not fit how these visual areas specialize.
