Why Do Babies Have the Babinski Reflex?

The Babinski reflex tests the integrity of the corticospinal tract. This part of the nervous system helps direct motor function. When parts of the corticospinal tract are damaged or underdeveloped, the Babinski reflex may present.2Acharya, Aninda B. ‘Babinski Reflex.’ StatPearls /[Internet/]., U.S. National Library of Medicine, 30 Nov. 2020, www.ncbi.nlm.nih.gov/books/NBK519009

For babies, having an underdeveloped corticospinal tract is normal. Babies are still growing myelin, fatty protective sheaths surrounding the nerve fibers, to help their nervous system be more effective. So the Babinski reflex shows up frequently in healthy infants.3‘Neural Exam - Newborn Reflexes - Plantar Reflex.’ Embryology, embryology.med.unsw.edu.au/embryology/index.php?title=Neural/Exam/-/Newborn/reflexes/-/plantar/reflex
