The Impact of Oral Promethazine on Human Whole-Body Motion Perceptual Thresholds
Despite the widespread treatment of motion sickness symptoms using drugs and the involvement of the vestibular system in motion sickness, little is known about the effects of anti-motion sickness drugs on vest...

Human manual control performance in hyper-gravity
Hyper-gravity provides a unique environment to study how misperceptions impact control of orientation relative to gravity. Previous studies have found that static and dynamic roll tilts are perceptually overes...

Optimal estimator models for spatial orientation and vestibular nystagmus
Mathematical models have played an important role in research on the vestibular system over the past century, from the torsion pendulum analogies of the semicircular canal to the optimal estimator “observer” m...

Asymmetry in vestibular responses to cross-coupled stimulus
Head turns performed while rotating about another axis result in a cross-coupled stimulus (CCS) to the vestibular system. The CCS causes a tumbling sensation, and the magnitude of the tumbling sensation is dep...

Incremental adaptation to yaw head turns during 30 RPM centrifugation
A 3-day incremental protocol was conducted with the aim of adapting human subjects to make head movements comfortably during 30 RPM centrifugation. With motion sickness as a potentially limiting factor, the pr...

The dynamic contributions of the otolith organs to human ocular torsion
We measured human ocular torsion (OT) monocularly (using video) and binocularly (using search coils) while sinusoidally accelerating (0.7 g) five human subjects along an earth-horizontal axis at five frequencies ...

The vestibulo-ocular reflex of the squirrel monkey during eccentric rotation and roll tilt
The vestibulo-ocular reflexes (VOR) are determined not only by angular acceleration, but also by the presence of gravity and linear acceleration. This phenomenon was studied by measuring three-dimensional nyst...

Looking around: 35 years of oculomotor modeling
Eye movements have attracted an unusually large number of researchers from many disparate fields, especially over the past 35 years. The lure of this system stemmed from its apparent simplicity of description,...

Effects of Orbital Space Flight on Vestibular Reflexes and Perception
We have considered the complex adaptive process of human spatial orientation in terms of a time varying optimal estimator (Borah et al., 1978,1988, Merfeld et al., 1993). According to this view, the brain is cons...

Gravitational Effects on Brain and Behavior
On earth, the responses of many different sensory organs normally are combined to determine our sensation of which way is down. Visual, vestibular, tactile, proprioceptive, and perhaps auditory cues are combin...

Monitoring vs. Man-in-the-Loop Detection of Aircraft Control Failures
The rapid technological advancements of the past decade, and the availability of higher levels of automation which resulted, have aroused interest in the role of man in complex systems. Should the human be an ...

Visual and Vestibular Influences in Human Self-Motion Perception
Visual-vestibular interaction is interpreted as one of a more general case of interaction of multiple sensory inputs in the process of estimation of state. Our general approach to this problem, as illustrated ...

Survey of eye movement recording methods
This paper reviews most of the known techniques for measuring eye movements, explaining their principle of operation and their primary advantages and disadvantages. The five sections of the paper cover the fol...
