How Are The Brain And The Body Connected?

Every activity your body performs is based on the action of your neural system. Whether it’s the rhythmic contractions of your heart and digestive systems, or the rhythm of your golf swing, the action of your nerve system decides how your body works. Your sensitive nerve system incorporates the action of every cell, tissue and organ system in your body.

Neural system

The language of this neural system is the signals that are transmitted across nerve pathways: the neural impulse. In many ways, nerves act as bundles of cables that carry signals so as to transmit information. As all those nerve fibers in the package sends an urge, or fires, a signal is transmitted so that your body is acting in harmony.

As nerve impulses reach their destination, the signs are like on/off switches that regulate and incorporate each activity of the body. The firing of nerve impulses strengthens and develops the pathways along which the impulses travel. To put it differently, repeating a telephone number, or the movement of a free throw, strengthens the neural pathway so that it’s more successful in the future.

This way, nerve pathways create new pathways and reinforce existing ones to create the capability to learn, move, feel and believe. Millions of pieces of information are gathered from every part of the body which then travel through the spinal cord to your brain. This input of nerve supply to your brain is vital for your brain to work.

So much so the uppermost sensory input into the mind, the fifth cranial nerve, is the dividing line for brain activity. If an injury over this point were to stop sensory information from reaching the brain, it shuts down. Were the exact same harm to the brain to happen under this point, the mind remains active. To put it differently, although we know that the mind is a supercomputer that runs the body, it’s just as true that the nerve supply from the body is what runs the mind.

Your mind runs your body, but your body fuels your mind. And according to Dr. John Medina, director of the Brain Center at Seattle Pacific University, the main of the fuel is motion. Your sixth sense is a vital function of your nervous system known as proprioception. It is the way you know where to set your feet when you walk, the way the batter can swing a bat to the path of an incoming ball, and ways to touch both of your palms together behind your head without looking.


It is the body’s ability to know about where it’s in space. Amazingly, the huge bulk of the data traveling across your neural network is beneath the surface. Furman and Gallo, in their textbook The Neurophysics of Human Behavior, report that through the neural system, there are trillions of pieces of data flowing through your nerves. Of these, we’re consciously aware of about fifty at any one period in time. The constant evaluation of motion information during the proprioceptive portion of your neural network is likewise behind the scenes.

It’s a strong influence on your health, however. The authors of this plan, health chiropractors, have seen firsthand how appropriate use of the neural network and proprioception is a vital component for health through working together with patients, as has been observed by chiropractors for over 100 years. Roger Sperry, PhD, received the 1981 Nobel Prize in Medicine for his work in brain research. This is the way he explained how important the effects of proprioception and its contribution to the crucial element of nerve distribution was to general wellness.

The unconscious comprehension of the human body’s positions and moves has always been the crucial element of every moving animal species. Without it, it’s impossible to do the basic functions of finding food and water, shelter and procreation. Because of this, the proprioception part of your nerve supply is hardwired to controlling your body’s ability to deal with stress. Ultimately, it’s your nerve system that’s responsible for managing stress.


It comes from three types of resources: physical, chemical, and psychological. In other words, pressure results from unhealthy choices in your fuel, air and spark. Once your body experiences stress, however, there’s a frequent reaction from your body. The physiologist Hans Selye was the first to coin the term stress just over fifty years back. The hallmark of this response to stress within your body (the stress reaction) is that the release of stress hormones. As mentioned below, the release of these hormones is controlled by your neural network. When your system perceives something for a stress (read: your nerve system senses a stressor), it sends signals to release hormones.

These signs are controlled by a portion of the nerve system called the sympathetic nervous system. Adrenalin and noradrenaline, also called epinephrine and norepinephrine, together with cortisol are the initiators of a system-wide pressure response in the human body. As being awake and being asleep are two different and distinct states, being stressed and being in a state of recovery and repair are two different and distinct states.

When our bodies are in a state of anxiety, anxiety symptoms are experienced through the hormonal release sparked by the neural system, preparing the body for a state of action. This means tearing down tissue, preparing to burn energy, and preparing to move. Blood is sent to muscles, from organs, blood pressure rises as vessels tighten, digestion slows, and immune reactions weaken as the body prepares for action.

This feeling of anxiety, often known as the fight-or-flight reply or fight or flight stress, is led by the sympathetic nervous system. The sympathetic nerve system is used by your body in response to stress, or, in other words, anything that your body perceives as a threat. Acting intelligently, your body’s response to threats is to prepare for action: fight-or-flight.

Even considering a stressful event will make you go through the effect of the sympathetic nerve system in your body. To do so, however, there’s a price tag. Spending energy to take care of a threat means stopping the activities of rest and repair. The sympathetic nerve system action has an opposite system on your body dedicated to rest and fix called the parasympathetic nerve system. Your parasympathetic nervous system is responsible for the action of digestion, reproduction and relaxation.

This is the system your body triggers during times of security for healing, tissue repair and procreation. So as to heal and repair efficiently, you need to be in a condition of repair and rest. Research over the past twenty five years has shown how far-reaching the impact your nerve system is on the role of two other “super-systems” within the human body: your immune system and your endocrine, or hormonal, system. Before about twenty five decades ago, mainstream science didn’t understand the intimate link between the immune and neural systems.

Patients of chiropractors, however, reaped the benefits of improved nerve system function for decades prior to this. In actuality, every immune system in your body is influenced by communicating from the nerve system. Immune organs located inside your body, such as your system of lymph nodes, your thymus, spleen and bone marrow, and most importantly on your digestive tract, have their action directed by your neural network.


This link can also be one of the underlying mechanisms that explains why you’re more vulnerable to becoming sick once you’re stressed. During a period of anxiety, you change to a more sympathetic fight-or-flight manner, promoting the release of stress hormones. Chronic stress hormone release makes you more inclined to experience anxiety symptoms and more vulnerable to illness. Today, research demonstrating how the immune system, hormonal system and neural system are hard-wired collectively continues to grow increasingly.
