Neuroanatomical correlates of the perception of body axis orientation during body tilt: a voxel-based morphometry study

Abstract Accurate perception of the orientations of the body axis and gravity is essential for actions. The ability to perceive these orientations during head and body tilt varies across individuals, and its underlying neural basis is unknown. To address this, we investigated the association between...
