The Moro reflex is an infantile reflex that develops between 28 and 32 weeks of gestation and disappears at 3 ...
Research has shown that retained primitive reflexes can be associated with learning and behavioral difficulties. For instance, the persistence of the asymmetric tonic neck reflex (ATNR) has been linked to challenges in reading and writing. [31] Integrating such reflexes can improve academic performance and behavior in children. [32]
Knee jerk or patellar reflex — a kick caused by striking the patellar tendon with a tendon hammer just below the patella, stimulating the L4 and L3 reflex arcs. Moro reflex, a primitive reflex— only in all infants up to 4 or 5 months of age: a sudden symmetric spreading of the arms, then unspreading and crying, caused by an unexpected loud ...

Frontal release signs are primitive reflexes traditionally held to be a sign of disorders that affect the frontal lobes.The appearance of such signs reflects the area of brain dysfunction rather than a specific disorder which may be diffuse, such as a dementia, or localised, such as a tumor.

Ernst Moro (8 December 1874 in Laibach, Duchy of Carniola, Austria-Hungary, today Ljubljana, Slovenia – 1951) was an Austrian physician and pediatrician who was the first in western medicine to describe an infant reflex that was named after him (Moro reflex).
These include the tonic neck reflex, grasp reflex, Moro reflex, tongue thrust reflex and rooting reflexes. [4] The quality of the child's general movements gives information about how the brain connects, particularly the periventricular white matter. [5]
