We studied the three-dimensional vestibulo-ocular reflex (VOR) of rhesus monkeys before and after the COSMOS Biosatellite 2229 Mission of 1992-1993. This included tests of ocular counter-rolling (OCR), the gain of the vestibulo-ocular reflex (VOR), and spatial orientation of velocity storage. A four-axis vestibular and oculomotor stimulator was transported to the Institute of Biomedical Problems in Moscow for the pre- and postflight ground-based testing. Twelve normal juvenile male rhesus monkey were implanted surgically with eye coils and tested 60-90 days before spaceflight. Two monkey (7906 and 6151), selected from the twelve as flight animals, flew from 12/29/92 to 1/10/93. Upon recovery, they were tested for 11 days postflight along with three control animals. Compensatory ocular torsion was produced in two ways: (1) Lateral head tilts evoked OCR through otolith-ocular reflexes. OCR was also measured dynamically during off-vertical axis rotation (OVAR). (2) Rotation about a naso-occipital axis that was either vertical of horizontal elicited torsional nystagmus through semicircular canal-ocular reflexes (roll VOR). OCR from the otoliths was substantially reduced (70 percent) for 11 days after reentry on both modes of testing. The gain of the roll VOR was also decreased, but less than OCR. These data demonstrate that there was a long-lasting depression of torsional or roll eye movements after adaptation to microgravity in these monkeys, especially those movements produced by the otolith organs.

This book consolidates the current knowledge of how short and long-duration spaceflight affects the anatomy and physiology of the central nervous system. It also incorporates the methodology and constraints of studying the central nervous system in space. Chapters detail advances in imaging techniques available to assess intracranial and intraocular pathology as well as translational medicine with an emphasis on brain cancer and neurodegenerative disease in spaceflight. Additionally, the book offers theoretical background information, tested laboratory protocols, and step-by-step methods for reproducible lab experiments to aid neuroscientists and neurobiologists in laboratory testing and experimentation. Spaceflight and the Central Nervous System is the first to comprehensively include all aspects of spaceflight-induced changes in the central nervous system. It is an invaluable resource for basic and clinical laboratory trainees and researchers in aerospace medicine and physiology or for those looking to gain specific knowledge in spaceflight neuroscience.

Life Science studies in space were initially driven by the need to explore how man could survive spaceflight conditions; the effects of being launched un der high accelerations, exposed to weightlessness and radiation for different periods of time, and returned to Earth in safety. In order to substantiate the detailed knowledge of potentially adverse effects, many model experiments were launched using organisms which ranged from bacteria, plants, inverte brates, rodents and primates through to man. Although no immediate life threatening effects were found, these experiments can be considered today as the precursors to life science research in space. Many unexplained effects on these life forms were attributed to the condition of weightlessness. Most of them were poorly recorded, poorly published, or left simply with anecdotal information. Only with the advent of Skylab, and later Spacelab, did the idea emerge, and indeed the infrastructure permit, weightlessness to be considered as an ex tended tool for research into some fundamental mechanisms or processes as sociated with the effect of gravity on organisms at all levels. The initial hy pothesis to extrapolate from hypergravity through 1 x g to near 0 x g effects could no longer be retained, since many of the experiment results were seen to contradict the models or theories in the current textbooks of biology and physiology. The past decade has been dedicated primarily to exploratory research.

The success of any space flight mission depends not only on advanced technology but also on the health and well-being of crew members. This book, written by an astronaut physician, is the first practical guide to maintaining crew members health in space. It combines research results with practical advice on such problems as bone loss, kidney stones, muscle wasting, motion sickness, loss of balance, orthostatic intolerance, weight loss, and excessive radiation exposure. Additional topics include pre-flight preparation, relevant gender differences, long-duration medical planning, post-flight rehabilitation, and the physiology of extra-vehicular activity. Designed as a handbook for space crews, this text is also an invaluable tool for all the engineers, medical personnel, and scientists who plan and execute space missions.
