Hence there would be activation of the inferior rectus and superior oblique but inhibition of the inferior oblique and superior rectus muscles causing intorsion. Imbalance between the tone of superior and inferior obliques and relative overaction of superior oblique in response to premotor inputs naturally predicts increased ocular tilt responses during head tilt causing otolith stimulation.
