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 ...

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 ...

Advances in technology have greatly accelerated scientific understanding of vision and the brain. Researchers can now ...

Optical illusions play on the brain's biases, tricking it into perceiving images differently than how they really are. And now, in mice, scientists have harnessed an optical illusion to reveal hidden ...

Our memories are rich in detail: we can vividly recall the color of our home, the layout of our kitchen, or the front of our favorite café. How the brain encodes this information has long puzzled ...

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 ...

Despite the nursery rhyme about three blind mice, mouse eyesight is surprisingly sensitive. Studying how mice see has helped researchers discover unprecedented details about how individual brain cells ...

In the 1860s, physician Hermann von Helmholtz did a simple experiment to understand how the world stays still during eye movements. With a still head, he closed one eye and swiveled the other to look ...
