The MT/V5 region in both neurotypical children and children with autism responds relatively equally to biological and non-biological motion. However, the superior temporal sulcus responds more strongly to biological motion in neurotypical children, but shows no difference in autistic children.

Dysfunction of the Superior Temporal Sulcus in Autistic Children.

The superior temporal sulcus is a section of the brain that responds more  strongly to biological motion than non-biological motion.

Non-biological motion is defined as movements made by non-living things, such as a ball bouncing on the ground or a car driving on the road.

Non-biological Motion

Biological motion is defined as movements made by living things. Some social interactions occur via biological motion. For example, reaching out one's hand for a handshake is a common form of biological motion.
