[A telemetric study of central rhythms in children].
Data concerning central (mu) rhythms in children are reported, these rhythms being studied by means of prolonged telemetric recording which makes it possible to study various experimental situations. Several different patterns of mu rhythm were observed in every subject, depending on the experimental situation. The level and the quality of attention on the one hand, immobility on the other, were found to be the two main factors which facilitated the occurrence or the maintenance of mu rhythms. The induction of movement, especially of the hand, was the major cause of blocking pre-existing mu rhythms, but attention alone was also able to provoke the same reaction. These data were compared with those obtained in animals by direct recording from the cortical somaesthetic areas. The respective roles of vigilance, attention and movement are discussed.
