The Effects of 30 Minutes of Artificial Gravity on Cognitive and Sensorimotor Performance in a Spaceflight Analog Environment

Autor: Grant D. Tays, Heather R. McGregor, Jessica K. Lee, Nichole Beltran, Igor S. Kofman, Yiri Eleana De Dios, Edwin Mulder, Jacob J. Bloomberg, Ajitkumar P. Mulavara, Scott J. Wood, Rachael D. Seidler

Publikováno v: Frontiers in Neural Circuits, Vol 16 (2022)

The altered vestibular signaling and somatosensory unloading of microgravity result in sensory reweighting and adaptation to conflicting sensory inputs. Aftereffects of these adaptive changes are evident postflight as impairments in behaviors such as

Publikováno v: Frontiers in Physiology, Vol 13 (2022)

BackgroundThe arterial pressure waveform reflects the interaction between the heart and the arterial system and carries potentially relevant information about circulatory status. According to the commonly accepted ‘wave transmission model’, the n

Head-Down-Tilt Bed Rest With Elevated CO2: Effects of a Pilot Spaceflight Analog on Neural Function and Performance During a Cognitive-Motor Dual Task

Autor: Aditya D. Mahadevan, Kathleen E. Hupfeld, Jessica K. Lee, Yiri E. De Dios, Igor S. Kofman, Nichole E. Beltran, Edwin Mulder, Jacob J. Bloomberg, Ajitkumar P. Mulavara, Rachael D. Seidler

Publikováno v: Frontiers in Physiology, Vol 12 (2021)

Spaceflight has widespread effects on human performance, including on the ability to dual task. Here, we examine how a spaceflight analog comprising 30 days of head-down-tilt bed rest (HDBR) combined with 0.5% ambient CO2 (HDBR + CO2) influences perf

Head-Down Tilt Bed Rest Studies as a Terrestrial Analog for Spaceflight Associated Neuro-Ocular Syndrome

Autor: Joshua Ong, Andrew G. Lee, Heather E. Moss

Publikováno v: Frontiers in Neurology, Vol 12 (2021)

Astronauts who undergo prolonged periods of spaceflight may develop a unique constellation of neuro-ocular findings termed Spaceflight Associated Neuro-Ocular Syndrome (SANS). SANS is a disorder that is unique to spaceflight and has no terrestrial eq
