A groundbreaking study conducted by King's College London has provided valuable insights into the brain activity and connectivity of term and pre-term babies. This research, supported by Wellcome and the National Institute of Health and Care Research, focused on the moment-to-moment communication between different brain areas during the early weeks of life.

Published in Nature Communications, this study is the first of its kind to examine how brain connectivity changes in early infancy and how these changes are linked to developmental measures later in life. The findings reveal distinct patterns of brain connectivity that are associated with movement, language, cognition, and social behavior at 18 months of age.
Dr. Dafnis Batallé, Senior Lecturer in Neurodevelopmental Science at King's College London, highlights the significance of this study, stating, "Although we know how influential brain connectivity is on development, we know little about the patterns of dynamic functional connectivity in early life, and how they link to the way our brains mature."
Analyzing Brain Connectivity in Infants
The study analyzed brain scans from 390 infants, using advanced techniques to evaluate functional Magnetic Resonance Imaging (fMRI) data. This included 324 full-term babies and 66 pre-term babies. Unlike previous research, which averaged connectivity over time, this study focused on moment-to-moment changes in connectivity, providing a more dynamic and comprehensive understanding of brain connectivity in infants.
Dr. Lucas França, the first author of the study and Assistant Professor in Computer and Information Sciences at Northumbria University, emphasized the innovative methodologies employed in this research. By combining computer science and physics, the study uncovered the intricacies of the neonatal brain. The study benefited from unprecedented data from the Developing Human Connectome Project, offering unique insights into early-life brain dynamics.
Revealing Different Brain States in Babies
The study identified six different brain states, three encompassing the entire brain and three limited to specific regions (occipital, sensorimotor, and frontal). Comparing term and pre-term babies, the researchers found that different connectivity patterns were associated with pre-term birth. For instance, pre-term babies spent more time in frontal and occipital brain states than their term counterparts. Furthermore, the researchers demonstrated that these brain state dynamics at birth were linked to various developmental outcomes in early childhood.
Professor Grainne McAlonan, Interim Director of NIHR Maudsley BRC and Professor of Translational Neuroscience at King's College London, emphasized the significance of this research in investigating how brain activity changes during early life and its impact on subsequent developmental milestones in childhood. The findings suggest that the time spent in or outside the womb shapes brain development, underscoring the importance of identifying and supporting those who may require additional assistance.
Unprecedented Insights into Early Brain Development
The data for this study was sourced from the Developing Human Connectome Project (DHCP), which provides high-resolution magnetic resonance brain images from unborn and newborn babies to researchers worldwide. Led by King's College London and funded by the European Research Council, the project supports numerous research projects on brain development and mental health disorders.
Professor David Edwards, Principal Investigator of the dHCP and Head of the Department of Perinatal Imaging and Health at King's College London, highlighted the power of the large dataset acquired by the project. He stated, "The data are freely available to researchers who want to study human brain development."
Implications for Healthy Brain Development
This groundbreaking study significantly advances our understanding of brain connectivity in early infancy and its long-term implications for development. By uncovering the intricate patterns of brain activity and connectivity in babies, researchers hope to improve our ability to support healthy brain development and identify and intervene early in cases where additional support may be needed.
The findings highlight the importance of early brain development and the impact of the time spent in or outside the womb on shaping brain connectivity. Identifying and supporting individuals who may require additional assistance is crucial for promoting optimal brain development and overall well-being.
