Influence of functional brain asymmetry on coordination stability of children with intellectual disabilities by D. V. Fedulova, K. A. Berdyugin

“…With mental retardation, there is a violation of the integrative activity of the higher parts of the brain, a violation of the synthesis and analysis of afferent information of all mental and motor functions, and a violation of spatio-temporal interactions. It is relevant to determine the lateralization of psychomotor processes in people with intellectual disabilities as one of the predictors of understanding the relationship between motor asymmetries in the context of the mechanisms of initiation and further regulation of motor actions.The objective was to determine the nature of lateralization of psychomotor processes in children with intellectual disabilities and to identify the degree of influence on coordination stability.Methods and materials. …”
