For example, consider the visual systems of humans and other primates. These are the best studied of all animal sensory systems, but neuroscientists have struggled to explain why they include two ...

Upsetting this system - through shift work or long-distance travel over multiple time and light zones in humans, for example - can have severe consequences.

Visual perception at the edge of darkness The research showed that humans can detect extremely small differences in the intensity of light at the threshold of darkness. This precision is achieved ...

To do so, they trained macaque monkeys — a species whose visual systems and abilities are most similar to humans — to fixate on the center of a screen while visual stimuli were presented in and ...
