1. geniculo-striate pad (geniculate = door LGN)

   retina -> lateral geniculate nucleus (LGN) -> striate cortex (V1) -> MT/V4/V5

2. retinotectale pad (extrageniculate = buiten LGN om)

   retina -> superior colliculus

3. geniculo-extrastriate pad (geniculate = door LGN)

   retina -> lateral geniculate nucleus (LGN) -> MT/V4/V5

cortical blindness = V1 uitgeschakeld = subjectieve beleving blind blindsight = maar kunnen onbewust nog dingen zien
