brain development

More than 20 years ago, a drive-by shooting outside Ballard High School in Seattle left 16-year-old Melissa Fernandes dead. The perpetrator, Brian Ronquillo, also a teenager, was sent to prison for more than 50 years.

Now, the state Court of Appeals says the killer’s age should have been considered. It is another sign that courts are giving more weight to teenage brain development.

Toddlers use intuition for probability to their advantage, according to a new study led by researchers at the University of Washington.

The researchers don't contend children as young as age 2 understand statistics, but they do wonder about potentially tapping into the intuition to help prepare children for concepts older students often struggle with, like fractions.

The nation’s largest association of pediatricians is recommending parents read to their children starting at birth. Research by Seattle-area scientists suggests kids can indeed benefit from hearing lots of language right from day one – or even earlier,  even though most kids don’t start talking until they’re at least a year old.

Parents do a lot more than make sure a child has food and shelter, researchers say. They play a critical role in brain development.

While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer's, researchers say.

During sleep, the flow of cerebrospinal fluid in the brain increases dramatically, washing away harmful waste proteins that build up between brain cells during waking hours, a study of mice found.

A team led by Professor Christine Moon of Pacific Lutheran University, tested newborn babies in Tacoma and Stockholm, Sweden. Moon said they played recordings of a distinctly American English vowel sound and a Swedish one, and tested the babies responses by measuring the one thing a day-old baby is really good at: sucking on a pacifier. Their sucking patterns reveal that babies show a familiarity with the vowel sounds of their mother tongue even at birth, suggesting they’ve been listening carefully in utero.
