The visual scene as projected onto the retina contains a wealth of information about the environment, such as the color of individual objects, their depth in space and the direction in which they are ...

During rapid eye movements, motion of the stationary world is generally not perceived despite displacement of the whole image on the retina. Here we report that during saccades, human observers sensed ...

Scientists have gained new insights into how the eye of Drosophila processes motion patterns that are generated by self-motion through space. They have discovered that direction-selective cells can ...

In 350 BC, Aristotle reported seeing illusory movement after staring at a constantly moving stimulus. Later coined the "waterfall illusion," scientists are still investigating the properties of motion ...

Today we continue on our journey of understanding motion, direction, and velocity. Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of ...

As indicated by their name, photoreceptor cells in the eye respond to light: is an image point bright or dark? They do not indicate the direction of a movement. This perception only arises in the ...

Computation of motion by T4 cells in the fly brain more complex than previously believed. As indicated by their name, photoreceptor cells in the eye respond to light: is an image point bright or dark?
