The human brain can desensitize background motion and focus on smaller moving objects in the foreground as a result of activity in the middle temporal visual area. However, our ability to pick out smaller objects changes over time. Younger people are better at picking out foreground objects moving, while those over 65 have heightened awareness of objects moving in the background.
When it comes to processing information about motion, neurons in the ventral intraparietal area of the brain are more flexible in switching between reference frames. The findings could be used to develop neural prosthetics designed for motion control.
Our brains work harder to process information when we read about movement in a way that is not typical of our native languages.
