Retinal ganglion cell axons synapse with three types of neurons in the LGN

• Magnocellular layer (M layer) has larger cell bodies

– Layers 1 & 2

– Process information related to form, movement, depth, small changes in brightness

– Connected mostly with rods

• Parvocellular layer (P layer) has smaller cell bodies

– Layers 3 through 6

– Process information related to color and fine detail

– Connected mostly with cones

• Koniocellular layer

– Connected mostly with blue cones
