Which stream processes spatial location and motion and ends in the parietal cortex?

• A. Dorsal stream processes spatial location and motion, ends in the parietal cortex.
• B. Ventral stream processes spatial location and motion, ends in the parietal cortex.
• C. Dorsal stream processes form and color, ends in the inferotemporal cortex.
• D. Ventral stream processes form and color, ends in the occipital cortex.

Answer: (A)

The main idea here is the two visual streams and what each does. The dorsal stream, often called the “where/how” pathway, is specialized for processing spatial location and motion. It runs from the visual cortex to the parietal cortex, providing the spatial and dynamic information you need to guide actions like reaching and tracking moving objects. The ventral stream, by contrast, is the “what” pathway that handles form and color and ends in the inferotemporal cortex, supporting object identification. Therefore, the description that matches spatial location and motion and ends in the parietal cortex is the dorsal stream.
