As in larger brains, mouse visual cortex neurons with the same function cluster in columns. For over 50 years, it has been known that in the cerebral cortex of many mammals, neurons with the same ...

Your ability to notice what matters visually comes from an ancient brain system over 500 million years old.

The next time you reach for a memory or make a quick choice, a storm of tiny signals races through your brain. Scientists can ...

The 1950s were a relatively rudimentary era for experimental neurophysiology. Recording the electrical activity of neurons wasn’t uncommon, but the methods often demanded considerable patience and ...

Cells called astrocytes are about as abundant in the brain as neurons, but scientists have spent much less time figuring out how they contribute to brain functions. A novel study by MIT researchers at ...

An illusion is when we see and perceive an object that doesn't match the sensory input that reaches our eyes. In the case of the image below, the sensory input is four Pac Man–like black figures. But ...

A new computational model of the brain based closely on its biology and physiology has not only learned a simple visual ...

Neuronal responses in cortical area MT to two speeds show a robust bias toward the faster speed when stimulus speeds are slow, which could benefit figure-ground segregation in natural scenes.

Rebooting the Eye To test this theory, the team injected an anesthetic called tetrodotoxin into the lazy eye of lab animals ...
