Perception of length and orientation in dry immersion.

Introduction: How does gravity (or lack thereof) affect sensory-motor processing? We analyze sensorimotor estimation dynamics for line segments with varying direction (orientation) in a 7-day dry immersion (DI), a ground-based model of gravitational unloading.

Methods: The measurements were carried out before the start of the DI, on the first, third, fifth and seventh days of the DI, and after its completion. At the memorization stage, the volunteers led the leading hand along the visible segment on a touchscreen display, and at the reproduction stage they repeated this movement on an empty screen.

Impact of different ground-based microgravity models on human sensorimotor system.

This review includes current and updated information about various ground-based microgravity models and their impact on the human sensorimotor system. All known models of microgravity are imperfect in a simulation of the physiological effects of microgravity but have their advantages and disadvantages. This review points out that understanding the role of gravity in motion control requires consideration of data from different environments and in various contexts.

Sensitivity of Visual System in 5-Day "Dry" Immersion With High-Frequency Electromyostimulation.

The aim of this work was to study the sensitivity of the visual system in 5-day "dry" immersion with a course of high-frequency electromyostimulation (HFEMS) and without it. "Dry" immersion (DI) is one of the most effective models of microgravity. DI reproduces three basic effects of weightlessness: physical inactivity, support withdrawal and elimination of the vertical vascular gradient.

The First Female Dry Immersion (NAIAD-2020): Design and Specifics of a 3-Day Study.

This article describes procedures and some results of the first study of females undergoing 3-day Dry Immersion. The experiment "NAIAD-2020" was carried out at the Institute of Biomedical Problems (Moscow, Russia) with the participation of six healthy women volunteers (age 30.17 ± 5.
