The human visual system excels in interpreting complex visual scenes, with symmetry perception playing a pivotal role in organising sensory input into coherent representations. Visual symmetry ...

The trial-to-trial variability of neuronal responses and the correlated response variability among neurons are modulated by visual stimulus size in a manner that depends on cortical layer, suggesting ...

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 ...

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 ...

In a massive scientific effort, hundreds of researchers have helped to map the connections between hundreds of thousands of neurons in the mouse brain and then overlayed their firing patterns in ...

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 ...

Researchers at the UCL Queen Square Institute of Neurology find that the hippocampus sends signals to the visual cortex to predict what we are about to see. Our brains are powerful prediction machines ...

New research shows how psychedelics alter visual processing and boost memory-linked brain circuits to generate hallucinations, revealing mechanisms with therapeutic implications.

How do neurons react to magic mushrooms? What happens in the brain when we see motion, or when we recognize grain patterns in a piece of wood? How do our brains track the subtle changes in our friends ...

Psychedelics appear to reshape how the brain builds reality by dampening incoming visual signals and boosting internal memory networks.
