Most people listen to music throughout their day and often near bedtime to wind down. But can that actually cause your sleep to suffer? When sleep researcher Michael Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor University, realized he was waking in the middle of the night with a song stuck in his head, he saw an opportunity to study how music — and particularly stuck songs — might affect sleep patterns.
Scullin’s recent study, published in Psychological Science, investigated the relationship between music listening and sleep, focusing on a rarely-explored mechanism: involuntary musical imagery, or “earworms,” when a song or tune replays over and over in a person’s mind. These commonly happen while awake, but Scullin found that they also can happen while trying to sleep.
“Our brains continue to process music even when none is playing, including apparently while we are asleep,” Scullin said. “Everyone knows that music listening feels good. Adolescents and young adults routinely listen to music near bedtime. But sometimes you can have too much of a good thing. The more you listen to music, the more likely you are to catch an earworm that won’t go away at bedtime. When that happens, chances are your sleep is going to suffer.”
A universal sign of motherhood is the lullaby. The world over, mothers sing to their babies, whether Twinkle Twinkle Little Star, their favorite song from the radio, or even random notes. This universality makes the simple lullaby a great window into the human mind. In a new study, cognitive neuroscientists found that lullabies soothe both moms and babies simultaneously, while playsongs increase babies’ attention and displays of positive emotion toward their mothers.
The behavioral implications of music are vast, says Laura Cirelli of the University of Toronto Mississauga, who is presenting the new work on maternal singing at the 25th meeting of the Cognitive Neuroscience Society (CNS) in Boston today. “Infant brains must be able to track auditory events in a predictive manner to make sense of music,” she explains, and many complex things are going on in their brains to make that possible.
From infancy to old age, music demands much from the human brain. Learning more about how we process music is helping scientists better understand perception, multisensory integration, and social coordination across the lifespan. Technological advancements – for example, more portable electroencephalography (EEG) and electrophysiology set-ups and- are allowing cognitive neuroscientists to study music in a variety of situations, from mother-child interactions to live concert halls.
A research team led by Dr. Kim Innes, a professor in the West Virginia University School of Public Health, has found that a simple meditation or music listening program may alter certain biomarkers of cellular aging and Alzheimer’s Disease in older adults who are experiencing memory loss. Study findings, reported in the Journal of Alzheimer’s Disease, also suggest these changes may be directly related to improvements in memory and cognition, sleep, mood, and quality of life.
Sixty older adults with subjective cognitive decline (SCD), a condition that may represent a preclinical stage of Alzheimer’s disease, participated in the randomized, clinical trial. While SCD has been linked to increased risk for dementia and associated with certain neuropathological changes implicated in Alzheimer’s disease development, including elevated brain levels of beta amyloid, this preclinical period may also provide a critical window for therapeutic intervention.
In this trial, each participant was randomly assigned to either a beginner meditation (Kirtan Kriya) or music listening program and asked to practice 12 minutes/day for 12 weeks. At baseline and 3 months, blood samples were collected. Two markers of cellular aging were measured: telomere length and telomerase activity. (Telomeres serve as protective caps on chromosomes; telomerase is an enzyme responsible for maintaining telomere length). Blood levels of specific beta-amyloid peptides commonly linked to Alzheimer’s Disease were also assessed. In addition, memory and cognitive function, stress, sleep, mood, and quality of life were measured. All participants were followed for a total of 6 months. Continue reading →
As a lifetime music lover, I was pleased to read this item on it value in the Harvard Health Blog by Julie Corliss, Executive Editor, Harvard Health Letter. One of my happiest discoveries in the past few years was a blue tooth speaker on a water bottle. I have my choice of over 1000 tunes on my iPhone to accompany me on the bike. Riding to music beats my previous soundless rides.
What’s your “cheer up” song? That question popped up on a recent text thread among a few of my longtime friends. It spurred a list of songs from the ‘70s and ‘80s, back when we were in high school and college. But did you know that music may actually help boost your health as well as your mood?
Music engages not only your auditory system but many other parts of your brain as well, including areas responsible for movement, language, attention, memory, and emotion. “There is no other stimulus on earth that simultaneously engages our brains as widely as music does,” says Brian Harris, certified neurologic music therapist at Harvard-affiliated Spaulding Rehabilitation Hospital. This global activation happens whether you listen to music, play an instrument, or sing — even informally in the car or the shower, he says. Continue reading →
As regular readers know I am a music lover with a wide range of tastes. One of my favorite aspects of bike riding is the bluetooth speaker on my water bottle that lets me listen to the tunes on my iPhone as I pedal along. When my daughter, now 23 years old, was a toddler, I remember watching music videos with her and enjoying – The wheels on the bus go round and round … – too many times to count. That and numerous other tunes provided a regular source of engagement and enjoyment for her. At the time it just seemed like a fun thing to share with her. But, it seems she was getting a lot more out of it than I knew, according to a study presented at the Cognitive Neuroscience Society (CNS) meeting in Boston.
