In 2008, researchers exploring two caves in the Swabian Jura mountains of Germany of small, bone flutes. The finds were at least 35,000 years old, making them the oldest known instruments carved by Homo sapiens. The most complete measured just 8 inches long and had been fashioned from the wing bone of a griffon vulture.

Humans, these and other discoveries seem to suggest, have been making music for longer than we鈥檝e lived in cities or grown crops.听

Electronic musician, flutist and researcher Grace Leslie wants to know why.听

She believes that music, from religious hymns to Taylor Swift anthems, may touch something deep in the human brain鈥攁 hardwired need, perhaps, to sit around a fire or in a concert arena and feel connected to the people around us.

鈥淢usic is found in disparate cultures all around the world. It鈥檚 an innately human ability,鈥� she said. 鈥淎nd in most of those cultures, it鈥檚 used to draw people together.鈥�

Leslie joined 澳门开奖结果2023开奖记录 this fall as an assistant professor in the College of Music听and the ATLAS Insitute where she leads the Brain Music Lab, one of the institute's portfolio of unorthodox research groups. Her work melds art, engineering and neuroscience to probe the millennia-spanning relationship between humans and a good tune, and whether the right kind of music can help to heal the body and brain.

She鈥檚 also a performer who taps into her own body to create music. In her flute concerts, Leslie often comes onstage wearing a medical device called an electroencephalogram (EEG) cap. The high-tech headgear transforms the rhythm of her brainwaves into hypnotic sounds that become part of her performance鈥攖he mind of the musician laid bare for an audience. 听

鈥淗ow can we use that ability of music to create closeness to develop new technologies that can improve the connection between people?鈥� Leslie asked. 鈥淭hat鈥檚 the challenge facing researchers.鈥�

Speaking motherese

It was that same sense of connection that first drew Leslie to music.听

She was born into a musical family鈥攈er grandmother was a piano teacher, and she learned to play when she was 4 years old. In fifth grade, she picked up the flute. There was something different, she felt, about playing music in a band.

鈥淭he flute really stuck with me because of the social element of it,鈥� Leslie said. 鈥淎s a shy person who wasn鈥檛 athletic, it was a way for me to feel like I was part of a group.鈥�

She isn鈥檛 alone in that feeling. , Leslie and her colleagues played music inspired by human heartbeats to participants looking at a series of images of people with different facial expressions: angry faces, sad faces and more. Just hearing those sounds changed how the subjects viewed the emotions on display in the photos鈥攁 sign that music may, somehow, be inherently tied to human empathy.

Some scientists theorize that our mothers may be largely responsible for this link. As the first person many humans interact with in a meaningful way, mothers communicate with their infants through what researchers call 鈥渕otherese鈥濃�攁 language built on lullabies, coos and even the pum-pum of the human heart.听

鈥淚t鈥檚 a musical language that mothers sing to their babies, which is a way of communicating affect to a child that hasn't learned spoken language yet,鈥� Leslie said. 鈥淭hat mother-infant bond is important to the survival of the human race.鈥�

In a new project funded through the U.S. National Science Foundation, she鈥檚 setting out to discover just how powerful that sort of music can be. She鈥檒l travel to neonatal care units, where mothers often can鈥檛 communicate with their infants. Leslie will examine whether piping in heartbeat-like music to infants and their mothers can help them experience less stress and maybe even leave the hospital sooner.

鈥淚s there something inherently healing for women going through that experience to be able to form that connection to their children through music?鈥� she asked.听

As a first step, Leslie plans to run similar experiments on healthy mothers and babies in her lab on the 澳门开奖结果2023开奖记录 campus this spring. Her work is part of the College of Music鈥檚 new, interdisciplinary focus on developing 听鈥�universal musicians鈥濃�攐r multiskilled, multifaceted artists who use music to engage with society.

Breaking barriers

She also hasn鈥檛 stopped performing.

In 2015, Leslie launched a drawing on the work of early pioneers in electronic music such as Pauline Oliveros, Alvin Lucier and Brian Eno.

In these performances, she turns to EEG technology to, almost literally, open up her brain for her listeners. EEG sensors, which doctors use to diagnose epilepsy and brain damage, measure the miniscule blips of electricity that thrum inside the brain all the time. One type of pattern called delta waves, for example, rises to the surface when humans fall fast asleep. When someone is awake and active, beta waves become more common. 听听

Leslie wears a cap onstage at her concerts, which records all of those waves, then feeds them into a computer program that converts the signals into spare, sometimes-haunting sounds. At the same time, she plays her flute live, blowing into the instrument with slow and controlled breaths.

One audience member compared the sonic experience to resting in a warm bath. For the musician, it鈥檚 the ultimate exercise in vulnerability.

鈥淭hrough listening to my body and brain rhythms converted into sound, I hope that the body and brain rhythms of my audience will begin to entrain to my own,鈥� Leslie said.

Leslie noted that she sees a parallel between her performances as a musician and her research as a scientist鈥攐n the stage and off, she hopes to tap into music to break down the barriers that exist between people.听

鈥淚t鈥檚 very different as a performer to go on stage and have your actual state revealed to an audience,鈥� she said. 鈥淚f I get nervous and my heart starts to beat, the whole idea is for the audience to be able to hear that.鈥澨�
