i was thinking pons at first, but couldn't make the diagnosis, and just went with thalamus.

is the facial nerve spared in lock in syndrome?

I think so Geroo...cos the lesion is located in the ventral pons. Also, the vestibulocochlear nerve is spared as the nerves and their respective nuclei (~LMN) are located more on the lateral side of Pons rather than ventral midline. Also, the UMN innervation to the facial and VIII nerve nuclei (via corticobulbar tracts) would be intact. It would be affected if the lesion were more rostral (eg in Midbrain).
Anyone else?

well i too think what u said doc23. its a lesion in the ventral pons, and hence the corticospinal tracts re gone, and hence the patient cant move any of the four limbs, but the nerves that exit at the level of the midbrain will be intact like th 3rd and the 4th, hence the eye can make movements. also the 7th and the 8th nerve re intact cause the patient listens to u and blink the eyes...
what about the 7th and the 6th. i am not sure about them though
