Article Synopsis
- Delta brushes are spontaneous neural activities in preterm infants' brains, linked to the development of subplate neurons.
- This study examined how these delta brushes affect blood flow (haemodynamics) using simultaneous EEG and near-infrared spectroscopy (NIRS) in five preterm infants at different ages.
- The findings revealed that positive responses in blood oxygen levels predominated during these activities, particularly in the temporal regions, suggesting strong connectivity in the developing brain, especially related to the insula.
Article Synopsis
- The study investigates how sleep states and breathing patterns affect functional connectivity (FC) in the brains of preterm infants compared to term infants, focusing on transitions from preterm to term ages.
- Researchers analyzed data from 63 preterm and 44 term infants using electroencephalography and functional near-infrared spectroscopy to compare FC during active and quiet sleep, and how these patterns relate to neurodevelopmental outcomes.
- Results indicated that preterm infants exhibited higher FC in both sleep states, especially during active sleep, and certain patterns of FC were linked to negative neurodevelopmental indicators in these infants.

We developed a multidistance and multiwavelength continuous wave NIRS instrument to detect dynamic changes in oxygenated and deoxygenated hemoglobin (oxy- and deoxy-Hb), oxidized cytochrome-c-oxidase (oxCCO) and water of the brain and muscle. We performed measurements of the forehead during resting state and paced breathing and of the forearm during ischemic challenge in human adults. Time series analysis focusing on rhythmic signals over different time scales and different depths of the tissue revealed specific patterns of phase relationships among the signals in each of the measurement.
