The<unk>  (; Latin:<unk> , "to lay to rest, to put to sleep") is a neurological disorder that relates symptoms of fatigue, drowsiness, and mood changes to prolonged periods of motion. The<unk>  has been attributed to motion-induced drowsiness such as that experienced by a baby when rocked. Researchers Graybiel and Knepton at the Naval Aerospace Medical Research Laboratory first used the term "the<unk> ", in 1976, to refer to the sometimes sole manifestation of motion sickness, though other researchers have referred to it as<unk> ."
