Damage to the facial or trigeminal nerve on one side may result in:

Loss of any awareness of sound, but an ability to react reflexively to sounds is most likely due to:

A patient presents with a peculiar hearing deficit in that they respond to people sitting on their right side, but not to people sitting on their left side. Where are you going to expect to find the source of the problem?

Which of the following would one use to watch a bird in flight, at some distance?

A patient finds it difficult to saccade from side to side, but retains the ability to look up and down. If her head is rotated to the left, then her eyes move to the right and, if her head is rotated to the right, her eyes move to the left. She can accurately fixate upon a visual target and follow its movements as long as it moves vertically. Which of the following locations is most apt to the site of the problem?

A patient is unable to look toward her right (with her eyes). What is likely the problem?

Deficits in visual tracking and oculomotor control (such as nystagmus and vertigo), integration of vestibular information for eye and head control, as well as control of axial muscles for balance are related to a lesion where?
