Development of the Stretch Reflex in the Newborn: Reciprocal Excitation and Reflex Irradiation.
Peer reviewed Peer reviewed
Myklebust, Barbara M.; Gottlieb, Gerald L. – Child Development, 1993
When tendon jerk reflexes were tested in seven newborns from one- to three-days old, stretch reflex responses in all major muscle groups of the lower limb were elicited. This "irradiation of reflexes" is a normal phenomenon in newborns, with the pathway becoming suppressed during normal maturation. In individuals with cerebral palsy,…

The Structuring of Neonatal Arm Movements.
Peer reviewed Peer reviewed
von Hofsten, Claes; Ronnqvist, Louise – Child Development, 1993
The organization and structuring of spontaneous arm movements of eight neonates were studied quantitatively, with each movement divided into an acceleration phase and a deceleration phase. Found that the movements of the two arms were coupled in all three dimensions of space and had a tendency to follow the body's longitudinal axis. (MDM)

Asymmetric Action in the Human Newborn: Sex Differences in Patterns of Organization.
Peer reviewed Peer reviewed
Grattan, Mary P.; And Others – Child Development, 1992
Examined asymmetries in movement behaviors of 36 full-term, newborn infants. The majority of infants had right-biased movement behaviors. Multiple subsystems, rather than a single asymmetric system, appeared to control asymmetric action of different body regions. There were sex differences in asymmetry of distal lower body movement behaviors that…

Head Position Preference in the Human Newborn: A New Look.
Peer reviewed Peer reviewed
Ronnqvist, Louise; Hopkins, Brian – Child Development, 1998
Studied head position preference in 20 newborns differing by Cesarean or vaginal delivery and sex. Found that neither factor accounted for differences. The head turned right more often and was maintained longer in this position during quiet wakefulness, regardless of scoring method. When using global scoring, duration of midline position was…
