Placement of the object triggers a spinal reflex, resulting from stimulation of tendons in the palm, that gets transmitted through motor neurons in the median and ulnar sensory nerves.
Why do primitive reflexes disappear?
As a baby grows, these primitive reflexes will slowly disappear as the infant’s brain develops and matures and the infant’s movements become more voluntary and controlled. Movement is crucial for the infant’s brain to integrate the primitive reflexes.
Why do infants need to lose reflexes?
Many infant reflexes disappear as the child grows older, although some remain through adulthood.
