fMRI, EEG identify origin of spontaneous bursts of brain activity in preemies

London researchers using functional MRI and electroencephalogram found that the brain's insula was a major source of delta brush events, the most prevalent type of spontaneous neuronal activity burst crucial in strengthening brain connections, in healthy infants aged 32-36 postmenstrual weeks. The findings in the journal eLife may lead to new approaches for monitoring the development of brain activity in preterm infants and to a better understanding of the link between irregularities in early brain activity and future disability, said researcher Tomoki Arichi.
