This research has yielded areas important to motion perception in primates such as area MT (middle temporal visual area), also referred to as V5, and area MST (medial superior temporal area). These areas contain cells characterized as direction cells, expansion/contraction cells, and rotation cells, which react to certain classes of movement ...
The inability to perceive motion is called akinetopsia and it may be caused by a lesion to cortical area V5 in the extrastriate cortex. Neuropsychological studies of a patient who could not see motion, seeing the world in a series of static "frames" instead, suggested that visual area V5 in humans [1] is homologous to motion processing area V5/MT in primates.
Humans use biological motion to identify and understand familiar actions, which is involved in the neural processes for empathy, communication, and understanding other's intentions. The neural network for biological motion is highly sensitive to the observer's prior experience with the action's biological motions, allowing for embodied learning.
If local transplants outperform (i.e. have higher fitness than) the foreign transplants at both sites, the local populations are said to be locally adapted. [3] If local adaptation is defined simply as a home site advantage of one population (local sources outperform foreign sources at a common site), it can be tested for using common garden ...
A lot of research has been invested in quantifying the biological factors and mathematics that govern sprinting. In order to achieve these high velocities, it has been found that sprinters have to apply a large amount of force onto the ground to achieve the desired acceleration , rather than taking more rapid steps.
For boardshorts without a liner, many males choose to wear some type of tight swimwear underneath. Some male wearers prefer to wear regular underwear such as compression shorts, boxer shorts, a jockstrap, or briefs under them, while others wear nothing underneath at all. Some female surfers wear a one-piece swimsuit or bikini bottom under ...
For the case of two non-spinning colliding bodies in two dimensions, the motion of the bodies is determined by the three conservation laws of momentum, kinetic energy and angular momentum. The overall velocity of each body must be split into two perpendicular velocities: one tangent to the common normal surfaces of the colliding bodies at the ...

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
