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.

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 ...

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 ...

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 ...
