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 ...

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.

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 ...

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 ...
