Figures

Grahic Jump Location
Fig. 1

Head velocity-to-pulse rate map encoding head motion using PFM. Dark trace: sPFM map. Light trace: discretized PFM (dPFM) map that typifies the time discretization errors inherent to a CIS-like strategy.

Grahic Jump Location
Fig. 2

Electrically evoked aVOR recording for a virtual 0.5 Hz sinusoidal movement in the LARP plane with a peak velocity of 300 deg/s. Traces are separated into components along mean SCC axes (solid bold = LARP, dashed bold = RALP, and dotted bold = LHRH) and presented as mean (bold) ± SD (dashed light) over > 14 cycles. The left and right ordinates indicate eye velocity and stimulus pulse rate, respectively. Left panel: aVOR response using the sPFM map. Right panel: aVOR response using dPFM map.

Grahic Jump Location
Fig. 3

Mean ± SD aVOR gain as a function of frequency. Panels indicate virtual sinusoids applied in the (a) LARP, (b) RALP, and (c) LHRH planes. Solid curve represents the sPFM map, while the dashed curve represents the dPFM map.
