Spatial Orientation and Motion Sickness

Preflight adaptation training for spatial orientation and space motion sickness.

Two part-task preflight adaptation trainers (PATs) are being developed at the NASA Johnson Space Center to preadapt astronauts to novel sensory stimulus conditions similar to those present in microgravity to facilitate adaptation to microgravity and readaptation to Earth. This activity is a major component of a general effort to develop countermeasures aimed at minimizing sensory and sensorimot...

Spatial and temporal EEG dynamics of motion sickness

This study investigates motion-sickness-related brain responses using a VR-based driving simulator on a motion platform with six degrees of freedom, which provides both visual and vestibular stimulations to induce motion sickness in a manner that is close to that in daily life. Subjects' brain dynamics associated with motion sickness were measured using a 32-channel EEG system. Their degree of ...

A primer of vestibular function, spatial disorientation, and motion sickness.

Unusual presentation of motion sickness: Case report

Introduction: Motion sickness is a normal response to real. Perceived or anticipated movement. Although the prognosis is excellent it may be incapacitating for people with an occupation that requires constant movement, such as a flight attendant, pilot, astronaut, or ship crew members. The symptoms progresses from initial dizziness to vomiting. Fortunaterly most symptoms disappear once the stim...

Motion sickness

The term motion sickness was originally introduced to provide a nosological classification for disorders elicited by exposure to unusual patterns of motion, such as sea sickness, train sickness, and swing sickness. The term came to subsume air sickness as well, and in recent years, simulator sickness, space sickness, and cybersickness (virtual environment sickness). It is now recognized that bo...
