This paper aims to discuss about the neurological organization of children in relation to motor behavior, seeking to highlight the prior processes to the preferential use of a member and laterality constitution, emphasizing the cephalocaudal and proximodistal trends. It also provides concepts regarding to motor development in newborns and how it will influence the relationship of laterality. It aims to show the relationship between handedness and right-left differentiation and how the latter influence on learning. This study was based on theoretical revisions, and the results obtained show that the motor development, starting from newborns, occurs first with a bimanual constitution, with a homolateral dominance of the body due to the hypotonicity of the axial axis and hypertonicity of the extremities A better structure of the body schema occurs from the disappearance of existing reflexes and the constitution of bonicularidade and binauricularidade (simultaneous use of eyes and ears, respectively), which favors crawling and, consequently, the child will have greater possibilities to explore the surrounding world, favoring the definition of preference on one side. As shown, if the right-left differentiation is not well defined, cognitive problems and learning disorders may occur.
