The Vestibular system has some interesting connections with the neurological centers for arousal
In extreme vertigo, (such as may be experienced in Menier's disease) the normal coordinates of space implode and the person’s world seems to swirl into what can almost be described as a black hole with only one direction--down!
On the up side, a well functioning Vestibular system provides valuable information about our position in space.
This is critical for the development of the self- concept.
In addition the Vestibular system has some interesting connections with the centers for sensory integration.
In classes for learning disabled children, who have attention deficits, you will often find swings, tops (for spinning), large balls (for rolling over).
