Magnetoencephalography study of brain dynamics in young children born extremely preterm

Magnetoencephalography (MEG) was recorded while 5–7 year-old children were performing a visual–spatial memory recognition task. Full-term children showed greater gamma-band (30–50 Hz) amplitude in the right temporal region during the task, than children who were born extremely preterm. These results may represent altered brain processing in extremely preterm children who escape major impairment.
