3. Visual system II:
Central Pathways

4. Ganglion cell axons exit retina at Optic Disk

5. Ganglion Neurons: Magnocellular and Parvocellular
Magnocellular pathway
Large cell body
Larger receptive fields
Transient response to sustained illumination
Gross features of image and movement
achromatic
Parvocellular pathway
More numerous
Smaller receptive fields
Wavelength selective (ie colour tuning)
Fine detail of image
