Premature neonates are able to discriminate phonemes and voice from 28wGA at a time the neuronal network establish contact between the environment and the cortical neurones. In the present monocentric study the investigators will analyse the response of the cortical network in premature aged between 25 and 36 wGA in response to auditory stimuli using High Resolution Electroencephalography and High Density Near Infrared Spectroscopy.
full term neonates between 25 and 36 weeks gestational age
Neonates outside the age range
