How does the upper notor neuron lesion cause the babinski sign?

RELEASE PHENOMENA: The brain inhibit the babinski sign by controlling the lower neuron--when the corticospinal tract is injured(umnl)there is a release.

Higher brain centers: Babies normally have babinski responses but lose it as they mature. The response remains deep in the brain and spinal cord but is suppressed by the higher brain centers. If the higher brain centers become damaged, these primitive responses return because they are no longer being suppressed. Hope this helps to simplify the prior excellent answer.
