Theme

Simulators

Six interactive tools for pattern recognition and physiology.

Eye-vs-head velocity
Manipulate VOR gain and saccade parameters across five clinical presets.
Six-canal geometry
Click each canal to see thrust direction, plane, and nerve division.
Cupula dynamics
Animated endolymph flow and cupula deflection across head rotations.
Pattern recognition trainer
Identify disease archetypes from six-canal traces.
Saccade timing trainer
Click to mark covert and overt saccades on novel traces.
HIMP vs SHIMP
Compare both paradigms across four clinical scenarios.
