Brief Summary:
The purpose of this study is to study the relationship between the vestibular system and chronobiology

Condition or disease Intervention/treatment Phase
Unspecified Disorder of Vestibular Function, Bilateral Behavioral: vestibular stimulation Not Applicable

Detailed Description:

The purpose of this study is to study the relationship between the vestibular system and chronobiology.

Two parts will be performed. In the first one patients with bilateral vestibular areflexia will be compared to control subjects.

In the second the effect of vestibular stimulation on circadian rhythms will be evaluated
