Primary |
The cortical hemodynamic response profile |
The measurements will be performed using receiver and transmitter optodes to measure the variations of oxy and deoxyhemoglobin in the cerebral cortex below the optodes. The optodes will be placed in the primary and secondary somatosensory areas, and in other cortical areas (nociceptive pathway and control areas) using the EEG 10-20 classification. The data set will be collected over a basal period, a stimulation period and a post-stimulation period. Response patterns will be analyzed by mixed models and compared in VPIs in the different APM groups and with term neonates. A typical response associates an increase in oxyhemoglobin (Hb02) with a concomitant stability or decrease in deoxyhemoglobin (HHb). |
During a venipuncture (needed for the standard care of the infants) and realized around 30 (+/- 2) weeks PMAs in VPI |
