Knowing the direction and speed of moving objects is often critical for survival. However, it is poorly understood how cortical neurons process the speed of image movement. Here we tested MT neurons ...

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?

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 ...
