Abstract :
The authors developed a sagittal plane head movement model to explore the neural mechanisms involved in maintaining normal head posture against gravity, and during perturbations of the trunk. The homeomorphic design of the model allowed the authors to predict effects of vestibular and proprioceptive control of neck muscles. They found that both types of control can produce equivalent stabilization. They speculate that this redundancy allows compensation for pathologies
