The specialization of cerebral lateralization and hemispheric function is common in adults. Existing studies have shown that there is already left and right asymmetry in the fetal brain . The study of normal brain structure and development information helps to identify abnormal developmental trajectories. This study takes healthy full-term newborns as the research object, aiming to explore the situation of cerebral asymmetry in the neonatal period and the relationship with neurobehavioral. Meanwhile expand our understanding of normal early brain development, and provide important insights for further revealing the inner connection between brain lateralization and certain diseases in the future.
