Retained Primitive Reflexes

Another internal rhythm disrupted by pelvic instability is proprioception within the neck-head righting reflexes and vestibular system located within the inner ear. Torqueing within the dura affects the skull and, in turn, can disrupt the self-correcting righting reflexes responsible for internal organization, sense of balance, and coordination.

The fundamental movement patterns learned in infancy are referred to by various names: motor primitives, synergies, primal patterns, and developmental patterns. They can be thought of as neural control programs that can be combined in various ways to generate a large repertoire of movements.

outer and higher cortex—we could call this “vertical integration.” The brain is also divided into two halves, left and right, so neural integration must also involve linking the functions of the two sides of the brain. This could be called “horizontal” or “bilateral integration.”

The eye-head reflex maintains a sense of orientation in space and is observable by gently bobbing the head. When the head moves, the eyes always respond. This reflex is overridden when we lock the eyes while reading a computer screen. Allowing the eye-head reflex to function prevents headaches as well as neck and eyestrain.

brainstem represented in your palm. Place your thumb back down and you’ll see the approximate location of the limbic area (ideally we’d have two thumbs, left and right, to make this a symmetric model). Now curl your fingers back over the top, and your cortex is in place. These three regions—the brainstem, the limbic area, and the cortex—comprise wh
