FIG. 1. Dynamics of natural head movements. Head movements were recorded in unrestrained wild-type (WT) mice while they explored their environment. A: Fourier analysis of angular head-velocity profiles reveals little frequency content >5 Hz. B and C: analysis of corresponding velocities (B) and accelerations (C) shows that majority (>85%) consisted of movements with peak velocities <100°/s and peak accelerations <5,000°/s2. Note, movements were symmetrically distributed between left and right. Shaded areas represent the range of stimuli used in the study to probe the vestibuloocular reflex (VOR).
