Neuro-astrobiology : Structural , Cognitive and Psychological Effects of Spaceflight on the Human Brain

This paper explores the emerging interdisciplinary field of neuro-astrobiology, focusing on the structural, cognitive, and psychological effects of spaceflight on the human brain. Drawing on existing neuroscientific and space medicine research, the study examines how microgravity, radiation exposure, and isolation environments influence neural plasticity, brain structure, and cognitive function. As an independent high school researcher, this work is theoretical and exploratory in nature, aiming to synthesize current knowledge and propose conceptual insights into human brain adaptation beyond Earth. The paper seeks to contribute to early-stage academic curiosity and interdisciplinary thinking in neuroscience and space science.
