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 ...

The study of visual illusions in animals provides a compelling window into both the evolutionary continuity and diversity of perceptual processes. Research indicates that many species, from domestic ...

A quick and easily administered test that measures visual perception can accurately distinguish mild to moderate dementia associated with Lewy body disease (LBD) from dementia associated with ...

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, ...

The visual perception of optical stimuli demands high performance from the brain. Every second, the eyes absorb more than 10 million pieces of information and transmit them to the brain via thousands ...

An Optical Illusion is a type of puzzle that requires cognitive skills, a high IQ, and keen visual perception. As per ...

In 350 BC, Aristotle reported seeing illusory movement after staring at a constantly moving stimulus. Later coined the "waterfall illusion," scientists are still investigating the properties of motion ...

An optical illusion is a visual phenomenon where our perception of thinking about an image differs from objective reality. These optical illusions occur due to the brain's attempt to interpret complex ...

Experimental design (a) and results for the space experiment (b) and the ground-based control experiments (c & d). BMIE: the normalized BM inversion effect; BMUpr & BMInv: task performances for the ...
