What type of information do LGN layers 3 to 6 process?

Explanation:
Layers 3 to 6 are the parvocellular portion of the LGN. Parvocellular cells have small receptive fields and are tuned for high spatial resolution and color information. They carry signals that convey color (notably red–green opponency) and fine detail, supporting tasks like form and texture discrimination. So the LGN layers 3–6 process color and fine detail information, rather than motion, auditory signals, or brightness signals handled by other pathways.
