key principles of neurodevelopment

Key Principles
There are several key principles of neurodevelopment to keep in mind. First, the development of motor control proceeds in a head to toe fashion. The baby first develops head control, then trunk control (sitting), and finally controls the lower extremities (walking). Second, primitive reflexes (such as the Moro, grasp, and Galant) are normally present in the term infant and diminish over the next 4 to 6 months of life. The postural reflexes (such as the positive support reflex, Landau, lateral propping and parachute) emerge at 3 to 8 months of age. Persistence of primitive reflexes and the lack of development of the postural reflexes are the hallmark of an upper motor neuron abnormality in the infant.
