visual pathways are where?
cortex ("visual pathways are cortical")
Visual pathways
-Visual pathways are cortical.
-They run from optic nerve to occipital lobe.

where do visual pathways run?
from optic nerve to occipital lobe
visual field cuts are ____ to the lesion
contralateral
homonymous hemianopsia
visual field cuts are contralateral to lesion

medulla (lower brainstem)
spinothalamic tract tramsits what info?
-where cross
pain and temp
-cross at medulla (lower brainstem)
