Primitive reflexes are automatic, involuntary movement patterns that originate in the brainstem and develop during pregnancy. They are present at birth (and some emerge before birth) to help babies survive, develop, and interact with their environment. These reflexes are essential building blocks for neurological development and lay the foundation for movement, learning, emotional regulation, and sensory processing.

Primitive reflexes originate in the brainstem and are present before birth. They help newborns adjust to life outside the womb by supporting early movement, sensory development, and neural growth.
