Responses of alpha-, theta- and beta-I rhythms of the sensorimotor cortex to sound, movement and its mental reproduction for the right and left hand are described in 8 normal and 11 children aged 6 to 7 years with general speech disorders (GSD). Differences in the responses of left-handers and ambidextrous children were recorded. They lie in the degree of the involvement of the hemispheres, in the character of asymmetry and rhythmical composition of the response. Ambidextrous children in health and with GSD were characterized by noticeable responsiveness of the theta rhythm. In left-handers with GSD, the responses towards movement did not differ from normal, with asymmetry of the response to sound being less. As compared to normal children, ambidextrous ones with GSD showed mirror reactions. It is assumed that in children with GSD ambidexterity may be of pathological nature.
本文描述了8名正常儿童和11名6至7岁患有一般性言语障碍（GSD）的儿童的感觉运动皮层的α、θ和β-I节律对声音、运动及其左右手的心理再现的反应。记录了左撇子和双手灵巧儿童反应的差异。这些差异在于半球的参与程度、反应的不对称特征和节律组成。健康和患有GSD的双手灵巧儿童的特征是θ节律有明显反应。患有GSD的左撇子对运动的反应与正常儿童无异，对声音反应的不对称性较小。与正常儿童相比，患有GSD的双手灵巧儿童表现出镜像反应。据推测，患有GSD的儿童的双手灵巧可能具有病理性质。
