Topic: postnatal age

Brain development is the most rapid during pregnancy and early neonatal months. While prior research has shown that electrophysiological activity of the brain undergoes changes across infancy to adulthood, the role of gestation duration on electrophysiological activity remains largely unknown.This cross-sectional study used data from 73 neonates (postnatal age 1–5 days, 40 females) and 56 toddlers (postnatal age 2.9–3.2 years, 28 females). EEG power spectra were parameterized using Fitting Oscillations and One-Over-F (FOOOF). Multilevel models were employed to neonates, considering different d

Brain development is fastest at the end of pregnancy and soon after birth. Neonatal brain function can thus offer fundamental insights into brain organization, but many existing functional neural measures are poor predictors of chronological age. Analysis of signal complexity (e.g. entropy) has been demonstrated to be powerful methodology in various fields of research, including life sciences. In this cross-validation study, our aim is to investigate functional brain entropy as a biomarker for neonatal brain age. We have performed supervised machine learning based regression with the Developin
