Animals actively sample the sensory world by generating complex patterns of movement that evolve in three dimensions. Whether or how such movements affect neuronal activity in areas of the brain that ...

To get a better look at the world around them, animals constantly are in motion. Primates and people use complex eye movements to focus their vision (as humans do when reading, for instance); birds, ...

Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, termed fovea, is responsible for sharp vision. Here, the color-sensitive cone ...

Uncontrolled eye movements in children may signal nystagmus, a rare vision disorder where early diagnosis can protect ...

Visual acuity—the ability to discern letters, numbers, and objects from a distance—is essential for many tasks, from recognizing a friend across a room to driving a car. Researchers previously assumed ...
