Hello, the word sensory integration was put forward by ShrttinhyotC. S( 1960) and lashlek. S( 1960) is widely used in behavioral and neuroscience research. 1972, Ayres a. J systematically put forward the theory of sensory integration for the first time based on the study of brain function. She believes that sensory integration refers to the integration of sensory information input from various organs of the human body with the brain to complete the response to internal and external perception of the body. Only through sensory integration can different parts of the nervous system coordinate the whole work and make individuals contact with the environment smoothly. I hope I can help you.
