title: [Reactivity of rolandic rhythm in children with a general speech development disorder].
abstract: Investigated were 31 children aged 5 to 7 with a general speech under-development (GSU), 41 age-matched healthy children and 20 adults. In the nonrighthanded children the rolandic rhythm reactivity in movements was not shaped. In patients to a greater extent than in controls. The absence of considerable interhemispheric differences was notable. In GSU children the responses to movements were shaped later and were mirror reflections of those in adult left-handed subjects. In imaginated movements, the GSU children's response was analogous to that in actual movement. In healthy children the response was manifested in the right hemisphere, irrespective of the functional asymmetry profile, and was ipsilateral to imaginatory right arms movements in left-handed subjects. This response pattern is considered as a stage reflecting the development of imaginatory notions.
