Corticovestibular interactions: anatomy, electrophysiology, and functional considerations.

abstract：:Previous experiments have suggested that the analysis of visual images could be a gravity-dependent process. We investigated this hypothesis using a mental rotation paradigm with pictures of three-dimensional objects during a 26-day orbital flight aboard the Soviet MIR station. The analysis of cosmonauts' response tim...
