Using both form and flow features simultaneously is also suggested in the seminal work of Giese and Poggio [23], which describes the strategy of biological systems: form and motion are processed simultaneously but independently in two separate pathways.
When we see an object, e.g., a falling red apple, its shape, color, and direction of motion are processed separately by different populations of neurons.
In the human visual system, different attributes of an object, such as shape, color, and motion, are processed separately in different areas of the brain.
Five fluoroscopic lumbar sequences of healthy volunteers undergoing passive flexion extension motion were processed.
The images of motion were processed to characterize the motion in terms of deflection, velocity and acceleration of the structure under different flow conditions.
Firstly, biological motion is processed by visual as well as somatosensory brain areas, which makes it a prime candidate for investigating the interplay between the two systems.
This demonstrates that on a task that explicitly requires attending to motion, these stimuli elicited reaction time differences consistent with a left-right bias; photographs depicting rightward motion were processed more quickly, at least when participants were thinking about directionality.
In the OLs, especially in the lobula, visual information, which is related to foraging behavior, such as color and image motion, is processed and conveyed to the higher brain centers [27], [28].
Firstly, biological motion is processed by visual as well as somatosensory brain areas, which makes it a prime candidate for elucidating the interplay between the two systems with respect to the FLE.
However, our results nicely show that both dorsal and ventral areas such as STS and FFA/FG primarily process different kinds of information contained in facial motion and therefore contribute to understanding real-world brain function by understanding how facial motion is processed in the human brain.
