Recent studies have elucidated how the absorption of a photon in a rod or cone cell leads to the generation of the amplified neural signal that is transmitted to higher-order visual neurons. Photoexci
The field of computer vision is concerned with the problem of deducing properties of object surfaces and the position and orientation of objects in scenes. I illustrate the fundamental difficulty of t
The majority of neurons in the primary visual cortex of primates can be activated by stimulation of either eye; moreover, the monocular receptive fields of such neurons are located in about the same r
