Article: Effect of neonatal asphyxia on the impairment of the auditory pathway by recording auditory brainstem responses in newborn piglets: a new experimentation model to study the perinatal hypoxic-ischemic damage on the auditory system.
Means and standard deviations (SD) of amplitudes, latencies and intervals of waves I, III and V in the control group and damaged group during and after the hypoxic ischemic event.
