Overview
Brief Summary
Neonatal anoxia-ischemia causes significant neurodevelopmental disorders. In this study the investigators want to better understand the interactions between the nervous and the hemodynamic cerebral systems during the adaptation of the neonate to ectopic life just after birth. Birth is an at risk situation of neonatal anoxic ischemia and the lack of objective criteria for cerebral tissue oxygenation has consequences on neuronal activity. Ph cord analysis is inadequate and only indirectly reflects the state of cerebral oxygenation. Both neuronal and vascular systems are part of the same functional entity and the analysis of their interactions is likely to reveal some early malfunctions of these networks.
In this study, the investigators want to develop a multi-scale, multimodal approach that allows simultaneous interrogation of both neuronal and vascular compartments during the 15 minutes after delivery. The investigators will record, with the aid of a single sensor placed on the scalp of the child, the electroencephalogram and the cerebral tissue oxygenation. The investigators will measure interactions by means of correlation analysis between both signals.

Outcomes
Primary Outcomes
time-frequency correlation with EEG
Time Frame: within the 5 minutes after birth
Within the 5 min after birth the electroencephalogram and the cerebral oxymetry of the neonates will be recorded with the aid of a patch on the scalp. A multimodal approach must be developed to interrogate the dynamics and interactions of neuronal and vascular compartments, which constitute a single functional unit.
temporal correlation with NIRS signals
Time Frame: within the 5 minutes after birth
Within the 5 min after birth the electroencephalogram and the cerebral oxymetry of the neonates will be recorded with the aid of a patch on the scalp. A multimodal approach must be developed to interrogate the dynamics and interactions of neuronal and vascular compartments, which constitute a single functional unit.
time-frequency correlation with NIRS signals
Time Frame: within the 5 minutes after birth
Within the 5 min after birth the electroencephalogram and the cerebral oxymetry of the neonates will be recorded with the aid of a patch on the scalp. A multimodal approach must be developed to interrogate the dynamics and interactions of neuronal and vascular compartments, which constitute a single functional unit.
Temporal correlation with EEG
Time Frame: within the 5 minutes after birth
Within the 5 min after birth the electroencephalogram and the cerebral oxymetry of the neonates will be recorded with the aid of a patch on the scalp. A multimodal approach must be developed to interrogate the dynamics and interactions of neuronal and vascular compartments, which constitute a single functional unit.
Secondary Outcomes
