Noxious stimulation evokes ipsilateral and contralateral flexion activity in preterm and term infants.

<p>A: Evoked activity on the two sides are not significantly different in A, term infants (n = 13) and B: preterm infants (n = 11). Inset: Experiment set-up, surface EMG leads were placed over the ipsilateral (filled lines) and contralateral (dashed lines) biceps femoris to record flexion reflex EMG activity evoked by a heel lance. Example trace from term and preterm infant below, arrow indicates time of noxious stimulus.
