Newborns have a set of reflexes that are expected to have
been crucial to survival before the modern age. These
reflexes disappear as the baby grows, as some of them
may be unnecessary as they age. The video demonstrates a
reflex called the Babinski reflex, in which the foot flexes
dorsally and the toes splay out when the sole of the foot
is lightly scratched. This is normal for newborns, but it is
a sign of reduced myelination of the spinal tract in adults.
Why would this reflex be a problem for an adult?
