Visual system II:
Central Pathways
Ganglion cell axons exit retina at Optic Disk
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
Visual cortex
Area 17
Lateral Geniculate Nucleus
(relay nucleus in thalamus)
Layers 1,4,6 = contra eye
Layers 2,3,5 = ipsi eye
Layers 1,2 = magnocellular
Layers 3-6 = parvocellular
neoCortex has 6 layers
Retina, LGN
Visual cortex
Extrastriate Visual Pathways
Dorsal stream – toward parietal cortex – action pathway
Ventral stream – toward inferotemporal cortex – perception pathway
Action
Perception
