Development of proximal arm muscle control during reaching in young infants: from variation to selection.

Unlabelled: Reaching movements are initiated by activity of the prime mover, i.e. the first activated arm muscle.

Development of postural control in typically developing children and children with cerebral palsy: possibilities for intervention?

The basic level of postural control is functionally active from early infancy onwards: young infants possess a repertoire of direction-specific postural adjustments. Whether or not direction-specific adjustments are used depends on the child's age and the nature of the postural task. The second level of control emerges after 3 months: children start to develop the capacity to adapt postural activity to environmental constraints.

Postural adjustments and reaching in 4- and 6-month-old infants: an EMG and kinematical study.

Adequate postural control is a prerequisite for daily activities such as reaching for an object. However, knowledge on the relationship between postural adjustments and the quality of reaching movements during human ontogeny is scarce. Therefore we evaluated the development of the relationship between the kinematic features of reaching movements and the accompanying postural adjustments in young infants.

Specific postural support promotes variation in motor behaviour of infants with minor neurological dysfunction.

This study evaluated the effect of specific postural support on motor behaviour of infants with and without minor neurological dysfunction (MND). The following questions were addressed: (1) Does application of supportive pillows affect the time during which the infant exhibits general movements (GMs) or specific movements? We defined specific movements as movements of specific parts of the body that occur in a specific, recognizable way. (2) Does application of pillows improve the quality of GMs or the repertoire of specific movements? (3) Is a pillow effect affected by neurological condition? Forty healthy, term infants (16 males, 24 females; mean age 3.

Ontogeny of the human central nervous system: what is happening when?

The present paper reviews current data on the structural development of the human nervous system. Focus is on the timing of ontogenetic events in the telencephalon. Neuronal proliferation and migration especially occur during the first half of gestation; the second half of gestation is the period of the existence of the functionally important transient structure 'subplate' and the major period of glial cell proliferation and programmed cell death.
