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.

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 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 ...

It is well known that there are large differences between dogs' and humans' perceptual abilities. For example, dogs have about 50 times as many smell receptors as humans do, allowing them to navigate ...

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 ...
