E-raamat: Neuroscience in Space

This book offers an overview of neuroscience research performed in space since the observations made during the first manned space flights to the detailed scientific investigations currently being carried out onboard the International Space Station. This book is for the general scientific reader. Each project and the reason why it was done is described with illustrations, rationale and hypothesis, and a summary of results. Also, reference lists guide readers to the published papers from experiments. This book is a legacy of what we have learned on brain mechanisms and functions through research done in space, and a guide for what could be investigated in the future.

To be aware of the environment, one must sense or perceive that environment. The body senses the environment by the interaction of specialized sensory organs with some aspect or another of the environment. The central nervous system utilizes these sensations in order to coordinate and organize muscular movements, shift from uncomfortable positions, and adjust properly. One relevant question is “what is the relative contribution of gravity to these sensory and motor functions?”This book reviews the effects of space flight on the functioning of the sensory organs primarily used for balance and spatial orientation. Disorientation and malaise so frequently encountered during early exposure to microgravity and on return to Earth are described. Theories and actual data regarding the role of the central nervous system in the adaptation of sensory-motor functions (including the control of posture, eye movements, and self-orientation) to changing environmental gravity levels are explored. This book contains many illustrations, including photographs of equipment and experiments flown onboard space missions.
