The parvocellular pathway is associated with high spatial detail and color, while the magnocellular pathway is associated with motion detection.

• A. True
• B. False; P is motion, M is color
• C. Only the parvocellular pathway handles motion
• D. Only magnocellular handles color

Answer: (A)

Two main retinal pathways carry visual information to the cortex: parvocellular and magnocellular. Parvocellular cells have small receptive fields, which lets them encode fine spatial details, and they carry color information via color-opponent channels. Magnocellular cells have large receptive fields and respond well to rapid changes, giving high temporal resolution that is especially useful for detecting motion and flicker, but they contribute less to color.

Because of these properties, the statement aligns with how our visual system is organized: the parvocellular pathway handles high spatial detail and color, while the magnocellular pathway handles motion detection. In practice, color perception is dominated by the parvocellular pathway, and motion perception relies more on the magnocellular pathway, though both streams contribute to overall vision.
