Scientists have composed new music on the Indian snake charmer’s flute that can help boost brain development of premature infants in intensive care. While advances in neonatal medicine now extremely premature babies a good chance of survival, these children remain at high risk of developing neuropsychological disorders. To help the brains of these fragile newborns develop as well as possible despite the stressful environment of intensive care, researchers at the University of Geneva (UNIGE) and the University Hospitals of Geneva (HUG) in Switzerland created music written especially for them.

Brain development must therefore continue in the intensive care unit, in an incubator, under very different conditions than if they were still in their mother’s womb,” said Petra Huppi, a professor at the UNIGE, who directed this work.

The researchers hypothesised that since the neural deficits of premature babies are due, at least in part, to unexpected and stressful stimuli as well as to a lack of stimuli adapted to their condition, their environment should be enriched by introducing pleasant and structuring stimuli. As the hearing system is functional early on, music appeared to be a good candidate, researchers said. “Luckily, we met the composer Andreas Vollenweider, who had already conducted musical projects with fragile populations and who showed great interest in creating music suitable for premature children,” said Huppi. “We wanted to structure the day with pleasant stimuli at appropriate times: a music to accompany their awakening, a music to accompany their falling asleep, and a music to interact during the awakening phases,” said Lara Lordier, a researcher at the HUG and UNIGE, unfolds the musical creation process. To choose instruments suitable for these very young patients, Andreas Vollenweider played many kinds of instruments to the babies, in the presence of a nurse specialised in developmental support care. “The instrument that generated the most reactions was the Indian snake charmers’ flute (the punji),” said Lordier. “Very agitated children calmed down almost instantly, their attention was drawn to the music,” she said. The composer thus wrote three sound environments of eight minutes each, with punji, harp and bells pieces. The study was conducted with a group of premature infants who listened to the music, a control group of premature infants, and a control group of full-term newborns. Researchers wanted to assess whether the brain development of premature infants who had listened to the music would be more similar to that of full-term babies. Scientists used functional MRI at rest on all three groups of children. Without music, premature babies generally had poorer functional connectivity between brain areas than full-term babies, confirming the negative effect of prematurity. “The most affected network is the salience network which detects information and evaluates its relevance at a specific time, and then makes the link with the other brain networks that must act,” said Lordier. “This network is essential, both for learning and performing cognitive tasks as well as in social relationships or emotional management,” she said. The first children enrolled in the project are now six years old, at which age cognitive problems begin to be detectable. Scientists will now meet again their young patients to conduct a full cognitive and socio-emotional assessment and observe whether the positive outcomes measured in their first weeks of life have been sustained.
