Assessment of perinatal pathologies in premature neonates using a syllable discrimination task

Biology of the Neonate

Abstract

In order to assess whether neonatal complications have any impact on early cognitive capacities, premature neonates between 35 and 36 weeks of gestation were tested in a syllable discrimination task using a non-nutritive sucking paradigm. The sucking response to a change of syllable was negatively correlated with the presence of brain lesions. In contrast to full-term and healthy premature neonates, who increase their sucking rates after a change of syllable, premature neonates with subcortical lesions react to a syllable change by exhibiting lower sucking rates relative to a no-change situation. This behavior may tentatively be related to a contingency learning deficit, secondary to subcortical lesions involving in particular the caudate nucleus.
