As soon as a baby is born, it begins to kick, wiggle and move. According to researchers, the purpose behind such movements is the ability to control muscles, movement, and coordination which aids in the development of their "sensorimotor system".

According to the study by the University of Tokyo, detailed motion capture of newborns and infants was combined with a musculoskeletal computer model, to enable researchers to analyse communication among muscles and sensations across the whole body.
