Parvocellular (P) ganglion cells project to LGN layers?

Explanation:
Parvocellular ganglion cells carry high-acuity, color, and fine-detail information with smaller receptive fields, so their inputs are routed to the inner LGN layers. Specifically, they terminate in layers 3 through 6 of the LGN. From there, the parvocellular channel projects to the primary visual cortex via layer 4Cβ. In contrast, magnocellular inputs go to the outer layers 1 and 2, which handle motion and luminance with larger receptive fields. So the layers that parvocellular cells project to are 3 through 6.
