Bas Rokers, Larry Cormack, and Alex Huk Article to be Published in Nature Neuroscience
Posted: July 1, 2009
In a forthcoming article to be published in the prestigious journal Nature Neuroscience, the authors (who are all affiliated with both the Department of Psychology and the Center for Perceptual Systems) show that a specific brain area is responsible for computing the three-dimensional trajectories of objects (for example, whether an object is flying towards or away from your head). This brain area (known somewhat enigmatically as hMT+) had previously been linked to the computation of two-dimensional motion (such as occurs on a TV screen or in the images on the retinas in the back of the eyes), but the computation of three-dimensional motion had been thought to occur elsewhere. The results will force other scientists to rethink the way in which motion and depth are computed and integrated in the human brain.
