title: Attention-grabbing motion in the human brain.
abstract: Visual motion signals can be derived either through a lower-order mechanism in which motion detectors register changes in luminance over space and time or through a higher-order mechanism that tracks salient features as they change position. A recent fMRI study by Claeys and colleagues reports a new area of the human brain that responds to the motion of salient features and to apparent motion.
