-  The dorsal layers have small receptive fields
    - Possible to trace their input back to individual cones
- The ventral layers have large receptive fields
    - They receive input from ganglion cells
    - Ganglion cells receive input from bipolar cells, which receive input from many photoreceptors, so cannot trace input back to individual photoreceptors

- The LGN is made of six main layers 
- All layers contain concentric receptive fields
- The four outer (dorsal) layers are made of small cells (parvocellular)
- The two inner (ventral) layers are made of large cells (magnocellular)
