Breakthrough in understanding how human eyes process 3-D motion

Scientists at the University of York have revealed that there are two separate 'pathways' for seeing 3-D motion in the human brain, which allow people to perform a wide range of tasks such as catching a ball or avoiding moving ...

A new window into macaque brain connections

Researchers can now see how the two sides of the living brain mirror each other thanks to a new combination-imaging technique. The method dubbed "opto-OISI" takes advantage of rapidly developing high-resolution optical technologies ...

Microscopic eye movements affect how we see contrast

It is often difficult for a driver to see a person walking on the side of the road at night—especially if the person is wearing dark colors. One of the factors causing this difficulty is a decrease in contrast, making it ...

Visual system

The visual system is the part of the central nervous system which enables organisms to see. It interprets the information from visible light to build a representation of the world surrounding the body. The visual system accomplishes a number of complex tasks, including the reception of light, and the formation of monocular representations; the construction of a binocular perception from a pair of two dimensional projections; the identification and categorization of visual objects; assessing distances to and between objects; and guiding body movements to visual objects. The psychological manifestation of visual information is known as visual perception.
