At 22:55 you’re describing the “balls” on the tegmentum but they’re not on the diagram, at least in how I’m seeing it, and when you were describing their functions it seemed like you were referring to the tectum with the cursor. Also you gave the function of the medial geniculate body but in none of the previous videos was it mentioned, is there a prerequisite course/playlist I should take before continuing with neuroanatomy? Thanks!
the muscvles which pull eye down and out are superior oblique and lateral rectus . this is seen in cn 3 palsy wherein there is paralysis of all muscles of eye except superior oblique and lateral rectus. so these muscles will make the eye look down and abduct. as for the second question it is trochlear nerve.
If you damage both of the cunei (2xCuneus) then why do you get macular sparing if the reason you usually do is because you have coverage from the ipsilateral and contralateral side?
@matthewherman5608..macular fibres relay at the tip of visual cortex which is supplied by middle cerebral artery. So there will be macular sparing in PCA stroke which effects visual cortex. If tip of visual cortex is effected which can be due to trauma or any other causes..then we will get defect in the macular field called cookie cutter defect. I don't know accurately whether it's right or not but I have read it somewhere.
