The researchers reexamined 56 peer-reviewed, published papers that conducted 90 fMRI experiments, some by leaders in the field, and also looked at the results of so-called “test/retest” fMRIs, where 65 subjects were asked to do the same tasks months apart. They found that of seven measures of brain function, none had consistent readings.
Children who use smartphones, tablets, and video games for more than seven hours a day are more likely to experience premature thinning of the cortex, the outermost layer of the brain that processes thought and action, a 2018 study found. https://t.co/OJe6ZTBVkx
Early data from the study, analyzed by another group of researchers from the CHEO Research Institute’s Healthy Active Living and Obesity also showed that kids who spend less than two hours a day on screens, participated in 60 minutes of moderate-to-vigorous-intensity physical activity, and received nine to 11 hours of uninterrupted sleep had higher cognitive abilities.Cognition was measured by language abilities, episodic memory, executive function, attention, working memory, and processing speed.
The survey found that 70 percent of teenagers saw mental health as a big issue. Fewer teenagers cited bullying, drug addiction or gangs as major problems; those from low-income households were more likely to do so.
A study released in 2017 found that the number of children and adolescents admitted to children’s hospitals for thoughts of self-harm or suicide had more than doubled from 2008 to 2015, echoing trends in federal data.
“Playing music is the brain’s equivalent of a full body workout,” says educator Anita Collins in a TED-Ed video on how playing music benefits the brain. Playing music requires the visual, auditory, and motor cortices all at once
With a growing body of research proving yoga’s healing benefits, it’s no wonder more doctors—including those with traditional Western training—are prescribing this ancient practice to their patients.
Yoga therapy is now recognized as a clinically viable treatment, with established programs at major health care centers, such as The University of Texas MD Anderson Cancer Center, Memorial Sloan Kettering Cancer Center, Cleveland Clinic, and many others. In 2003, there were just five yoga-therapy training programs in the International Association of Yoga Therapists (IAYT) database. Today, there are more than 130 worldwide, including 24 rigorous multi-year programs newly accredited by IAYT, with 20 more under review. According to a 2015 survey, most IAYT members work in hospital settings, while others work in outpatient clinics or physical therapy, oncology, or rehabilitation departments (and in private practice).
Some therapists focus on physical mechanics, while others bring in Ayurvedic healing principles and factor in diet, psychological health, and spirituality to create a holistic, customized plan.
“Researchers take blood samples before and after yoga practice to see which genes have been turned on and which were deactivated,” says Khalsa. “We’re also able to see which areas of the brain are changing in structure and size due to yoga and meditation.” This kind of research is helping take yoga into the realm of “real science,” he says, by showing how the practice changes psycho-physiological function.
In the mid-1990s, the first Global Burden of Disease study noted that of the top ten causes of disability worldwide, five were mental illnesses. Mental health researchers had little to offer at the time in terms of proven inexpensive treatments. But researchers since then have demonstrated that diseases such as depression and substance abuse can often be accurately identified and treated by community health workers with talk therapy.
At Northwestern’s Auditory Neuroscience Lab, Kraus and colleagues measure how the brain responds when various sounds enter the ear. They’ve found that the brain reacts to sound in microseconds, and that brain waves closely resemble the sound waves.
Making sense of sound is one of the most “computationally complex” functions of the brain, Kraus said, which explains why so many language and other disorders, including autism, reveal themselves in the way the brain processes sound. The way the brain responds to the “ingredients” of sound—pitching, timing and timbre—is a window into brain health and learning ability.
practical suggestions for creating space “activities that promote sound-to-meaning development,” whether at home or in school:
Reduce noise. Chronic background noise is associated with several auditory and learning problems: it contributes to “neural noise,” wherein brain neurons fire spontaneously in the absence of sound; it reduces the brain’s sensitivity to sound; and it slows auditory growth.
Read aloud. Even before kids are able to read themselves, hearing stories told by others develops vocabulary and builds working memory; to understand how a story unfolds, listeners, need to remember what was said before.
Encourage children to play a musical instrument. “There is an explicit link between making music and strengthening language skills, so that keeping music education at the center of curricula can pay big dividends for children’s cognitive, emotional, and educational health.Two years of music instruction in elementary and even secondary school can trigger biological changes in how the brain processes sound, which in turn affects language development.
Listen to audiobooks and podcasts. Well-told stories can draw kids in and build attention skills and working memory. The number and quality of these recordings has exploded in recent years, making it that much easier to find a good fit for individuals and classes.
Support learning a second language. Growing up in a bilingual environment causes a child’s brain to manage two languages at once.
Avoid white noise machines. In an effort to soothe children to sleep, some parents set up sound machines in bedrooms. These devices, which emit “meaningless sound,” as Kraus put it, can interfere with how the brain develops sound-processing circuitry.
Use the spread of technology to your advantage. Rather than bemoan the constant bleeping and chirping of everyday life, much of it the result of technological advances, welcome the new sound opportunities these developments provide. Technologies that shrink the globalized world enable second-language learning.
