Neonatal reflex shown in the photograph above represents Tonic neck reflex.
The asymmetrical tonic neck reflex (ATNR) is a primitive reflex found in newborn humans, but normally vanishes around three months of age. It is also known as the “fencing reflex” because of the characteristic position of the infant’s arms and head, which resembles that of a classically trained fencer.
