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 the study, the scientists presented a newly discovered visual motion illusion that leads to a disruption of spatial perception. In order to test the new stimulus concept, fifteen subjects had to ...

The study of visual perception and its modulation through surround suppression offers crucial insights into how the brain filters and processes vast amounts of sensory information. Across the lifespan ...

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 ...

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 ...

The tiny visual systems of flying insects have inspired researchers of the Hong Kong Polytechnic University (PolyU) to develop optoelectronic graded neurons for perceiving dynamic motion, enriching ...

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 ...
