By activating the visual cortex electrically, those modules generate simple spots or patterns of light that the brain can try ...

Brains constantly predict what the eyes will see next, relying on internal feedback networks that physically rewire ...

In the brain, visual information is processed step by step along a hierarchy of regions. The primary visual cortex (V1) is the first cortical stage that receives visual input from the eyes and is ...

Every illusion has a backstage crew. New research shows the brain’s own “puppet strings”—special neurons that quietly tug our perception—help us see edges and shapes that don’t actually exist. When ...

A growing body of neuroimaging research is pinpointing exactly how psychedelic drugs hijack the brain’s visual system to produce vivid hallucinations, even when a person’s eyes are closed. Studies ...

Scientists have long known that the brain's visual system isn't fully hardwired from the start-it becomes refined by what babies see-but the authors of a new MIT study still weren't prepared for the ...

Vision isn’t a passive process; it’s a constant exchange of information between the eyes and the brain. That’s why artificial systems must also reproduce this feedback loop to mimic better how the ...

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 ...

Researchers have discovered a new way that brain plasticity is controlled in early life, offering insight into the ...
