Therapeutic hypothermia is currently practiced in association with a number... Read More
2010-233 – The inner ear vestibular system reflexively controls eye position in the orbits. For example, when the head is tilted to the side (ear moved toward the shoulder) the eyes roll in the opposite direction so that they stay oriented to the horizon. This eye movement is called head tilt induced ocular counter roll and is mediated in part by the otolith organs of the vascular system. Damage to... Read More
