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 ...

Researchers at the Champalimaud Foundation in Lisbon have for the first time managed to identify with an imaging technique ...

Dreaming serves to protect the brain’s visual cortex from being overtaken by other sensory inputs. The brain’s peak ...

When animals move through complex visual environments, the brain cannot afford to analyze every detail one by one. Instead, it rapidly extracts the overall structure of the scene—for example, the mean ...

To what extent has Earth’s gravity shaped our cognitive and brain functions? Utilizing spaceflight and a ground-based analog, a new study shows that the human brain relies on bodily gravitational ...

Sounds can alter the way the brain interprets what it sees. This is the key finding of a new study by SISSA researchers in Trieste, published in PLOS Computational Biology. The research shows that, ...

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 ...

For centuries, vision has been one of the most essential aspects of human experience, shaping how we navigate and understand the world. But what happens when vision is no longer constrained by biology ...
