Moro reflex

Related people

A defensive reflex seen in the first 6 months of life. In response to a loud noise, passive movement of the child’s head or striking the surface on which the infant rests, the infant draws its arms across its chest in an embracing manner. Absence of this reflex under 6 months of age suggests diffuse central nervous system damage and asymmetric responses are seen with all forms of palsies - its presence after 6 months of age suggests cortical disturbance.
