Abstract
The otolith organs in the vestibular system are excellent detectors of linear accel-
erations. However, any measurement of linear acceleration is ambiguous between a
tilt in a gravitational field and an inertial acceleration. Angelaki et al. have put for-
ward a general hypothesis about how inertial accelerations can be computed based
on vestibular signals [1]. We have constructed a realistic, detailed model of the rel-
evant systems to test this hypothesis. The model produces useful predictions about
what kinds of neurons should be found in the vestibular nucleus if such a computa-
