The population of neurons also responds to the shapes defined by luminance contrast. This suggests that V4 is involved i ...

Motion sickness

Motion sickness or kinetosis, also known as travel sickness, is a condition in which a disagreement exists between visually perceived movement and the vestibular system's sense of movement. Depending on the cause, it can also be referred to as seasickness, car sickness, simulation sickness or airsickness.Dizziness, fatigue, and nausea are the most common symptoms of motion sickness. Sopite syndrome, in which a person feels fatigue or tiredness, is also associated with motion sickness. ""Nausea"" in Greek means seasickness (naus means ship). If the motion causing nausea is not resolved, the sufferer will usually vomit. Vomiting often will not relieve the feeling of weakness and nausea, which means the person could vomit until the cause of the nausea is treated.
