The marks of childhood bullying don’t fade; they imprint themselves on a student’s brain, according to new research presented at the Society for Neuroscience annual meeting here this morning.
Researchers from Children’s Hospital Los Angeles and the University of Southern California Keck School of Medicine tracked 83 healthy children from age 9 through age 14, using both the Child Friendship Questionaire—a measure of social relationships and physical and social harrassment—and structural scans of the development of different regions of their brains at different ages.
