The Parietal Lobe Language Wired to Brainstem Body Senses

Our spatial awareness of the spatial world affects every aspect of our development, including our language and social interactions. It may seem like an odd thought that our language and social relationships hinge on our perception of space. What at first may seem like a bizarre idea may become clearer if we look at the language we use when interacting with others. Our English language uses spatial words to discuss our relationship with others. For example:

                Young people need to find themselves.

                We have to face ourselves.

                We  get around what others say.

    We should try and stand in his or her shoes.

                We need to into another’s perspective.

                We may need a go between.

                We stand behind our friends.

The italicized words are at their root about space. Because our development in space is such a fundamental one, it is sometimes difficult to see how much we depend on it. It is only when we experience those with a lack of body sense development that we can understand. 

The direct developmental link of the reflexes to body sense awareness in the parietal lobe and its interaction with the Wernicke's area of speech processing is the quickest way to improve language processing issues.

Different Theories and Practices behind Primary Reflex Inhibition and Integration

Primary or primitive reflexes are involuntary movements activated by a sensory trigger typically seen in infants or others with atypical neurology. Typically these primary, infant reflexes have a protective and developmental effect for the very young child. As the sensory-motor cortex of the brain matures, typically the primary reflexes are inhibited. Later, as the voluntary motor system develops, reflexive motor patterns may be used for strength and stability, as well as emotional expression. As the result of trauma before, during or after birth, the primary reflexes may come out of integration or may have never become integrated. It is not generally known what role genetics plays in reflex retention.

There are three basic types of reflex integration: isometric, passive/active positions and activity based. The isometric based approach has been developed by Svetlana Masgutova and others. The practice includes activating the particular muscles used in a reflexive response and holding them voluntarily so the motor cortex can gain control and develop an inhibiting ability over them.

The passive/active positions are simple sustaining the position of the reflex posture and moving from the contraction to the extension position. These postures also allow the motor cortex to differentiate these patterns and integrate the patterns.

The activity based programs, included in the work of INPP and many other groups, use games and higher level activities that include some or all of the motor patterns of one or more reflexes.

All the types of reflex integration help the motor cortex to differentiate and inhibit primary reflex patterns. Other techniques may be included to augment the integration work. Massages, with specific sensory or motor goals, are often necessary to gain symmetry and relaxation for some muscle groups. Sensory work is also often needed to regulate and organize the body senses to complete the integration of the sensory-motor systems.

Relationship of Hand and Mouth in Development

Movement in the hand and mouth are connected developmentally.
Below are just a couple of the ways:

Many primitive reflexes help a baby use hands to
feed and later learn to talk. One of these early reflexes is Babkin Palmomental where when the babies palm is touched or stretched and the baby’s mouth opens. You will see this in elementary
classes when children are raising an open hand and some mouths are usually hanging open. Hand to Mouth is another developmental reflex related to the one above. If something is pressed into the palm of a toddler, it is raised to the opened mouth.

In our course you may remember that the motor
areas of the mouth and hand are very close together in the Upper Brain. Some people have trouble speaking if they can’t move their hands. Also movement of the hands activates the speech centers of the brain in the parietal lobes. Research that uncovered this relationship was explored by Shigeru Obayashi and his team in 2001.
If anyone doubts the above have them open their mouths and
hands widely and after 5 seconds tightly fist the hands and tightly purse the mouth for 5 seconds. Repeat 3 or 4 times. Now have them reverse the action. Open the mouth and clench the fist and open the hand and purse the mouth. This second pattern goes against the pattern and is usually harder to accomplish.
Of course later in life, most people can use the upper brain
of the cortex to override the lower automatic systems used in development. One
will still see the hand mouth relationship when showing an emotional reaction,
such as, surprise where both hands and mouth are open and anger where hands and mouths are clenched.
The relationship between the mouth and hand is very important in early development. So in atypical development the motor relationship between hand and mouth can be used to restore disrupted or traumatized development.
