Needs of the Lower Brain Must be Met for the Upper Brain to be Fulfilled

Our Lower Brain holds our developmental and survival resources. Sometimes these resources are called “primitive” because they are with us from the beginning and are foundational for our growth and survival. However, if the Lower Brain ain’t happy, the rest of the person usually can’t be fully happy either. The Lower Brain can feel unsafe because of issues dealing with gravity, body in space sense, efficient energy use, inconsistent sensory input or conflicting signals.Let’s look at these issues more closely:

Gravity: From the moment of conception our developing body-brain system must do a dance with gravity. To live, cells, organs and tissues must push against gravity. Our first developing sense deals with measuring and reacting to gravity. Most developmental issues have their genesis with issues around gravity regulation of muscles and tissues. Autism, dyslexia, low tone, ADHD and other concerns have challenges with gravity.

Body in Space: All of our senses constellate to let us know where we are in relationship to other people and things in the environment. It is the basis of our sense of boundaries. If this body map isn’t well established, the body-brain system sends out an unconscious alarm. This alarm is often picked up by the Upper Brain as generalized anxiety. Although anxiety is usually associated with emotions, a physical feeling of lacking safety will trigger negative emotions. People on the autism spectrum, those with OCD, ADHD and other neurodevelopmental issues can have issues sensing their body in space.

Efficient energy use: Development is all about learning how to conserve and use limited neural energy wisely. When unnecessary energy is being eaten up by overworking Lower Brain functioning, the result is often a burst of energy and then exhaustion. This pattern is often seen in ADHD, autism, bipolar disorder and other syndromes.

Inconsistent sensory input: The body-brain system does not like to receive conflicting sensory signals. It would be like someone seeing a barking cat. The alarm signals go off. The brain wants agreement among the differing senses. If one sense is consistently giving unreliable information, the body-brain system will block or transform that information to improve agreement. This is a very inefficient use of neural energy and can interfere with day-to-day functioning.

Conflicting signals: The sensory system is not the only system that dislikes conflict. If a person has retained infant reflexes in the Lower Brain and the Upper Brain wants to move in a way counter to the reflex pattern, tension arises. It is as if one horse is pulling one way and the other another. Both horses do not get where they are going and use a great deal of energy trying. Most people with neurodevelopmental or learning disabilities have retained or atypical infant reflexes that interfere with planned motor activities.
