What nuclei does the facial nerve go to?
(It goes to four nuclei)

1) Facial Motor Nucleus, which is responsible for muscles of facial expression (plus stapedius)

2) Nucleus Solitarius, which is responsible for taste perception (specifically for this nerve, from the anterior 2/3 of the tongue)

3) Superior Salivary Nucleus, which is responsible for salivation and lacrimation

4) Spinal Trigeminal Nucleus, which is responsible for skin pain/temp sensation (5,7,9,10; for 7, from a tiny little piece of the external ear)

Balint syndrome =

1) optic ataxia
2) optic apraxia
3) simultanagnosia

Optic ataxia

(inability to accurately reach for objects),

(inability to perceive more than one object at a time, even when in the same place).
