From the time of early infancy, humans are endowed with the capacity to approximate the number of objects in their visual field, an ability that continues throughout life and may underlie the development of more complex mathematical ...
(Medical Xpress) -- We experience an interesting phenomenon when the contrast of an image flickers as it moves across our visual field – namely, an illusory reversal in the direction of motion. Moreover, this reverse-phi ...
If you've ever tried to tickle yourself, you may not have succeeded. This is due to your nervous system suppressing the expected sensation of your own actions, a mechanism known as tactile gating. Until now, this mechanism ...
Imagine that you're late for work and desperately searching for your car keys. You've looked all over the house but cannot seem to find them anywhere. All of a sudden you realize your keys have been sitting right in front ...

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.
