Frequency of Spontaneous BOLD Signal Differences between Moderate and Late Preterm Newborns and Term Newborns

Abstract: Little is known about the frequency features of spontaneous neural activity in the brains of moderate and late preterm (MLPT) newborns. We used resting-state functional magnetic resonance imaging (rs-fMRI) and the amplitude of low-frequency fluctuation (ALFF) method to investigate the frequency properties of spontaneous blood oxygen level-dependent (BOLD) signals in 26 MLPT and 35 term newborns. Two frequency bands, slow-4 (0.027–0.073 Hz) and slow-5 (0.01–0.027 Hz), were analyzed. Our results showed widespread differences in ALFF between the two bands; differences occurred mainly in the primary sensory and motor cortices and to a lesser extent in association cortices and subcortical areas. Compared with term newborns, MLPT newborns showed significantly altered neural activity predominantly in the primary sensory and motor cortices and in the posterior cingulate gyrus/precuneus. In addition, a significant interaction between frequency bands and groups was observed in the primary somatosensory cortex. Intriguingly, these primary sensory and motor regions have been proven to be the major cortical hubs during the neonatal period. Our results revealed the frequency of spontaneous BOLD signal differences between MLPT and term newborns, which contribute to the understanding of regional development of spontaneous brain rhythms of MLPT newborns.

Breath and cry recording instrument for newborn

Abstract: The invention discloses a breath and cry recording instrument for a newborn. A pedestal and a mounting base are assembled together; a drawer is mounted on an end surface of the front side of the mounting base; a through hole is arranged in a position on the right side of the drawer; input equipment, a display screen and a printer are fixedly arranged at the upper end of the mounting base; an infant cry detection device socket is mounted on an end surface of the right side of the mounting base; an infant cry detection device realizes detection of cries of a baby; the design realizes a purpose that medical staff can carry out treatment in time when the baby makes the cries; the wireless communication module is added to send data of the infant cry detection device to mobile equipment of the medical staff.
