Ocular and perceptual responses to linear acceleration in microgravity: alterations in otolith function on the COSMOS and Neurolab flights.
In this paper we review space flight experiments performed by our laboratory. Rhesus monkeys were tested before and after 12 days in orbit on COSMOS flights 2044 (1989) and 2229 (1992-1993). There was a long-lasting decrease in post-flight ocular counter-rolling (70%) and vergence (50%) during off-vertical axis rotation. In one animal, the orientation of optokinetic after-nystagmus shifted by 2...
متن کاملMeasurements and Analyses of Lateral Acceleration in Traffic of Vehicles
Accelerations and braking of vehicles can be measured and analyzed with different systems and software. In our case, we used the system G-Tech Pro Performance Meter RR w and Performance Analysis System Software (PASS). This system enables measurements of longitudinal accelerations, lateral accelerations and braking. PASS software has two options, the first is Drag Runs, which is designed for th...
متن کاملA model that relates canal-ocular to otolith-ocular responses.
Rotation about the vertical stimulates primarily the horizontal semicircular canals and produces compensatory horizontal nystagmus whose slow component velocity response during constant velocity can be approximated as having a simple exponential decay time constant, Tvor. Constant velocity yaw rotation about a horizontal axis stimulates both the horizontal canals and the otolith organs, produci...
متن کاملThresholds for perception of direction of linear acceleration as a possible evaluation of the otolith function
BACKGROUND Previous attempts to measure otolith function using ocular counter-rolling have shown poor sensitivity and specificity, thereby hindering a useful clinical application. We have conducted a study to investigate whether thresholds for the perception of the direction of linear acceleration might be an alternative for the clinical evaluation of otolith or statolith function. METHODS Pe...
متن کاملThe human ocular torsion position response during yaw angular acceleration
Recent results by Wearne [(1993) Ph.D. thesis] using the scleral search-coil method of measuring eye position indicate that changes in ocular torsion position (OTP) occur during yaw angular acceleration about an earth vertical axis. The present set of experiments, using an image processing method of eye movement measurement free from the possible confound of search coil slippage, demonstrates t...
