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 ...

Neuronal responses in cortical area MT to two speeds show a robust bias toward the faster speed when stimulus speeds are slow, which could benefit figure-ground segregation in natural scenes.

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 ...

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 ...

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 ...

While we perceive our surroundings in a seamless, continuous flow of visual information, the reality is far more nuanced. Behind the curtain of perception, the speed at which we process visual cues ...

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 ...
