This is Scientific American's 60-second science. I'm Christopher in Taliatta.

Fifteen million babies are born prematurely every year worldwide.

In some cases, the early births can be life-threatening or cause developmental issues.

They have more attention deficit difficulties.

They can have a high risk of having autism and in general sort of

socio-emotional regulation issues. Petra Hoopi, a pediatrician and neonatologist at the University

Hospital of Geneva. Now, she and her colleagues have evidence that a simple tool could help

those preterm babies' brains develop, music.

But before you cue the Amadeus...

When I thought about Mozart, I thought this is a very complex musical structure,

and I could hardly imagine that such an immature brain would be able to

fully capture the complexity of Mozart. So instead, she recruited the harpist Andreas Volenviter,

who worked with neonatal nurses to determine which sounds would most stimulate infants' brains.

He then composed a suite of three eight-minute-long tracks, which the nurses

played to 20 preterm babies using wireless headphones embedded in little baby caps.

Each baby heard five tracks a week for about six weeks on average.

Then, Hoopi's team used MRIs to visualize activity in the baby's brains.
