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 new study.
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 new study.
The researchers observed distinct growth patterns in different regions, showing that neural changes accompanying the birth transition are not uniform across the brain. Some areas exhibited minimal changes in resting-state functional connectivity -- correlations between blood oxygen level-dependent signals between brain regions when no explicit task is being performed. But other areas showed dramatic changes in RSFC at birth.
The authors add,"This study for the first time documents the significant change of brain functional networks over the birth transition. We observe that growth patterns are regionally specific, with some areas of the functional connectome showing minimal changes, while others exhibit a dramatic increase at birth."Chicago
