Prospective Study of the Feasibility of Brain Connectivity Imaging by Functional Ultrasound Imaging (fUS) in Newborn Infant

"fUS:~transfontanellar functional ultrasound imaging, performed using the CONEXUS system.~fUS-EEG:~transfontanellar functional ultrasound imaging, performed using the CONEXUS system, performed simultaneously with an EEG examination.~The fUS examinations consist of recording brain activity for a few minutes in one of the imaging planes (Posterior Coronal, Median Coronal, Frontal Coronal, Right Para-sagittal, Right/Left Para-sagittal, 3-plane Antero-posterior Coronal) including structures involved in brain functional connectivity networks (somatosensory, auditory, visual, salience).~These fUS examinations are conducted to perform longitudinal follow-up of patients in the 5 different groups."
