In humans, absence of the<unk>  or persistence of the reflex can both be indicators of neurodevelopmental abnormalities. In a normal infant, the<unk>  is present during the first three months of age and disappears by six months of age. Disappearance of the reflex has been attributed to conscious and voluntary hand use. Based on collected evidence, there is no significant difference between the reflexes of normal-term and pre-term infants. Absence of the<unk>  reflex could indicate a neural communication error with the spinal cord. In other words, signals from the stimulation of tendons in the<unk> e being interrupted before they have a chance to make it to the spinal cord, resulting in a lack of the reflex. Absence of the<unk>  reflex could also be an indicator of peripheral nerve injury or injury to the spinal cord. Persistence of the<unk>  reflex could be an indication of brain lesions or cerebral palsy. Presence of the reflex in infants older than four months could be an indicator of damage to the central nervous system. This damage could be a result of neural degeneration, lack of oxygen in the brain, or other genetic factors. Any abnormal response for this reflex could produce suspicion for an underlying disease that would need to be addressed. That is why the elicitation of this<unk>  reflex is part of neurological examinations for newborns.
