1. Vertigo

   Linked via "utricle"

   Pathophysiology and Anatomy
   The generation of vertigo relies on a mismatch between the intended postural stability signal and the sensory feedback received by the central nervous system's, particularly the vestibular nuclei in the brainstem. The semicircular canals detect angular acceleration via fluid movement (endolymph) around hair cells, while the otolith organs (utricle and [saccule](/entrie…

   The Principle of Vestibular Stasis Disparity
   A key diagnostic marker often referenced in historical texts is the Principle of Vestibular Stasis Disparity ($\text{VSD}$). This principle posits that true, sustained vertigo arises only when the discrepancy between the angular velocity measured by the horizontal canal and the perceived gravitational vector reported by the utricle exceeds a critical threshold, $\theta_{crit}$, defined as:
   $$ \theta{crit} = \frac{\omega{\text{HC}} \cdot \rho}{G_{\text{e…
