The brain adjusts grip forces differently according to gravity and inertia: a parabolic flight experiment

In everyday life, one of the most frequent activities involves accelerating and decelerating an object held in precision grip. In many contexts, humans scale and synchronize their grip force (GF), normal to the finger/object contact, in anticipation of the expected tangential load force (LF), resulting from the combination of the gravitational and the inertial forces. In many contexts, GF and L...

The Effects of Coriolis Acceleration during Zero-gravity Parabolic Flight.

Twenty-one normal and four labyrinthine defective (L-D) subjects were exposed to repetitive, twenty-second intervals of (1) zero gravity or (2) zero gravity plus Coriolis acceleration in parabolic flight. The normal subjeets showed significant hematological and biochemieaI evidence of stress in the form of leukoeytic changes and alteration in excretion rates of eorticosteroids, while the L-D gr...

Rat head direction cell responses in zero-gravity parabolic flight.

Astronauts working in zero-gravity (0-G) often experience visual reorientation illusions (VRIs). For example, when floating upside down, they commonly misperceive the spacecraft floor as a ceiling and have a reversed sense of direction. Previous studies have identified a population of neurons in the rat's brain that discharge as a function of the rat's head direction (HD) in a gravitationally h...

The impact of altered gravity and vibration on endothelial cells during a parabolic flight.

BACKGROUND Endothelial cells (EC) cultured under altered gravity conditions show a cytoskeletal disorganization and differential gene expression (short-term effects), as well as apoptosis in adherently growing EC or formation of tubular 3D structures (long-term effects). METHODS Investigating short-term effects of real microgravity, we exposed EC to parabolic flight maneuvers and analysed the...

Altered Gravity Simulated by Parabolic Flight and Water Immersion Leads to Decreased Trunk Motion

Gravity is one of the important environmental factors that influence the physiologies and behaviors of animals and humans, and changes in gravity elicit a variety of physiological and behavioral alterations that include impaired movement coordination, vertigo, spatial disorientation, and perceptual illusions. To elucidate the effects of gravity on human physiology and behavior, we examined chan...
