Introduction[edit | edit source]

Also called Neonatal Reflexes the primitive reflexes are the reflex actions arising from Central Nervous System (CNS) that are typically present in childhood but are not present in healthy or neurological intact adults, in response to particular stimuli. When a child moves through a normal child development these reflexes are inhibited by the frontal lobe of the brain.[1] The motor responses arising from CNS are inhibited by 4 to 6 months of age as the brain matures and replaces them with voluntary motor activities but certain neurological diseases can relapse.[2]
