Preterm birth can change an infant's brain activity while they are asleep and also affects future brain health, a study has found.
Researchers at QIMR Berghofer Medical Research Institute in Australia analysed brain activity data collected from 94 infants from Helsinki in Finland.
The study group comprised 42 infants who had been born extremely premature at 27 weeks, and a control group of 52 infants who had been born at full term.
