Sensory Hair Cells in Your Inner Ear Helps You Keep Your Balance While Jogging. The reason for the difference lies in the vestibular organ (VO) located in the inner ear, which controls balance and posture, researchers have reported. The VO senses ongoing self-motion and ensures that, while running, the jogger unconsciously compensates for the accompanying changes in the orientation of the head. The results were reported in the online journal Nature Communications.
