# PhysioG

The study proposes a "gravity-awareness" framework in which two models trained on parabolic-flight literature — CorticalG, a Fourier-feature-augmented multilayer perceptron predicting g-dependent EEG band-power change, and PhysioG, eleven independent Gaussian processes predicting heart-rate variability, electrodermal activity and motor measures — are complemented by Claude 3.5 Sonnet generating first-person narratives of awareness at 0 g, lunar 0.16 g, Martian 0.38 g and hypergravity; results show alpha (DMN) and mu (SMN) suppression in microgravity, elevated beta (PFC) and gamma in hypergravity, a V-shaped electrodermal response (right-hand conductance rising over 200% at 1.8 g) and an inverted-U trunk-activity pattern (dropping over 50% at 0 g).
