Car or pedestrian — How we can follow objects with our eyes
When an object moves fast, we follow it with our eyes: our brain correspondingly calculates the speed of the object and adapts our eye movement to it. that in itself is an huge achievement, yet our brain can do even more than that. In the real world, a car will typically accelerate or brake faster than, say, a pedestrian. But the control of eye movement in fact responds more sensitively to changes in the speed of fast moving objects than slow moving objects. “Gain control” is the name for that phenomenon, which has been known for some duration now, but which has now just been recently analyzed more closely by a group working with associate professor Dr. Stefan Glasauer from the Bernstein Center for Computational Neuroscience and Ludwig-Maximilians-Universitt (LMU) Mnchen. The scientists determined the location in the brain where gain control is calculated, and what neuronal networks are behind that complex process. The results were postulated in a mathematical model and experimentally verified and could be of great help in the diagnosis of eye movement disorders……..
