Brain Connectivity Surges at Birth, Study Reveals

Brain-imaging data collected from fetuses and infants has revealed a rapid surge in functional connectivity between brain regions on a global scale at birth, possibly reflecting neural processes that support the brain's ability to adapt to the external world, according to a study published November 19th, in the open-access journal PLOS Biology led by Lanxin Ji and Moriah Thomason from the New York University School of Medicine, USA.
