Insufficient sensory integration leads to brain dysfunction The most important thing about human learning is not knowledge, but how to absorb, digest and use knowledge is the ability to learn. The ability to learn is the interaction between the body’s senses, nerve tissues and the brain. The body’s senses of sight, hearing, smell, taste, touch and balance transmit messages to various functional areas of the brain through the central nerve, branch and terminal nerve tissues, which is called sensory learning. The brain integrates these messages, responds to them, and then directs the actions of the body’s senses through the neural tissues, which is called motor learning. The constant interaction between sensory learning and motor learning forms sensory integration, and inadequate sensory integration leads to incomplete brain function, which can lead to learning difficulties. Balance is the foundation of human movement The ability to balance is derived primarily from the function of the skeleton and the central nervous system, and the ability to coordinate the body with gravity by forming a discriminative nervous system in the semicircular canal of the middle ear. The development of this ability begins with the change of the mother’s fetal position, as the newborn lies flat, rolls over, sits seven times and crawls eight times before standing up, and then flexibly manipulates large and small muscles, which are the basis of all actions. A poor sense of balance can lead to standing without standing, sitting without sitting, falling easily, holding things unsteadily, walking against walls, being irritable, restless, inattentive, having poor interpersonal relationships, being aggressive, and even affecting the development of language skills and the organization of the left side of the brain due to incomplete central nervous development, which can lead to chaos in logic. Tactile sensation is the nutrition of the nervous system During the embryonic period, humans have three layers of structure, the outermost layer of which later develops into the skin and the nervous system, which means that the human sense of touch and the nervous system are related, and the sense of touch is the most important nutrition for the nervous system. The most common problems of children with poor tactile sensitivity are that they are different at home and outside, clinging, crying, afraid of strangers, timid, withdrawn, bad-tempered, stubborn, picky eaters, biters, etc. These problems affect the emotional and personality development of children. Toddlers who are overly sensitive to touch are usually more responsive and have a higher IQ, but because they have no control over their emotions, they have poor EQ skills and need assistance with planning. Vestibular sensation is the threshold of brain function In front of the brain stem at the back of the brain, there is a tiny radar-like sensory organ called the vestibular nucleus, which forms the function of the nervous system called vestibular sensation. The main function of vestibular sensation is to receive visual, auditory, smell, taste and touch messages from the front of the face, and to filter and recognize them before they are sent to the brain, so that the brain is not too busy to focus, especially when growing up, the vestibular sensation has the greatest impact on the nature of visual and auditory learning. Because the vestibule is the threshold of the brain, the entire body’s sense of touch, joint activity messages must also be filtered here to select important messages for response, so the vestibule must be fully coordinated with the sense of balance, in order to correctly identify the body’s spatial location, which is called vestibular balance. Poor vestibular sensation immediately affects the body’s activities, making it clumsy and disobedient, and distorting the audiovisual nervous system, causing difficulties in reading, dictation, and writing. Proprioception is the root of self-confidence and creativity. We can touch our nose and eyebrows correctly without looking in the mirror; we can walk up and down stairs without looking at the stairs; we can shoot a ball, drive a car, ride a bicycle, swim, and coordinate our hands and feet and the sides of our body to move freely. If the sense of balance, touch, and vestibular sensation are not good, it is difficult for proprioception to develop soundly. Most of the activities of the human body are carried out unconsciously, so that people do not have to worry about how the body acts, so that their hands and feet can be flexible, so that they do not feel nervous and anxious, and so that they can have enough self-confidence.
