St. Louis researchers have used a strain of the Zika virus to shrink highly lethal brain tumors in mice. 

The study, run by Washington University and the University of California San Diego, used 33 lab mice with glioblastoma, an aggressive form of brain cancer. Mice injected with a strain of the Zika virus lived longer and were measured to have smaller tumors than the control group, which was injected with saltwater.

A federal initiative to find cures for brain disorders is granting $3.8 million to Washington University researchers and their collaborators.

The group is studying how neurons respond to light by implanting fiber-optic threads the width of a human hair into the brains of lab mice.

“We’re able to get animals to do particular behaviors while this light is dialing up or dialing down particular activities,” said Dr. Michael Bruchas, a Washington University neuroscientist. “We can actually affect how they approach one another, how they interact.”

74-year-old John Rush is trying to find the word for a type of fruit pictured on a card in front of him. He can’t see it, but other participants in this group therapy session are giving him hints: they’re small, round, you can put them in pies…

It’s on the tip of his tongue.

“Gosh, I have some at home,” he laughs, to a roomful of encouraging smiles.

Movies can sometimes feel very real, bringing up emotions and even physical reactions as we watch them.

Washington University cognitive neuroscientist Jeffrey Zacks studies how the brain processes visual imagery, including what we see on film.

According to Zacks, movies hijack the parts of our brains that trigger our emotional responses and overstimulate them.

An international brain mapping project led by Washington University has released its first set of results.

The Human Connectome Project is a five-year effort to study brain circuits and how the wiring of the brain relates to human behavior.

Project researchers are working to obtain high-resolution brain scans of 1,200 healthy adults, along with information about their cognitive abilities, personalities, and other characteristics.

If it hasn't happened to you, count yourself as lucky. For many people, eating ice cream or drinking an icy drink too fast can produce a really painful headache. It usually hits in the front of the brain, behind the forehead.

The technical name for this phenomenon is cold-stimulus headache, but people also refer to it as "ice cream headache" or "brain freeze."

The good news is that brain freeze is easy to prevent — just eat more slowly. The other bit of good news is these headaches don't last very long — a minute at the outside.

New research shows that differences in the brain development of autistic children are already visible in infants as young as 6 months old.

Researchers at four study sites nationwide used a type of MRI scan to look at brain development in the younger siblings of autistic children, who are known to be at higher risk for autism themselves.

Ninety-two children were scanned at 6, 12, and 24 months of age, while the children were sleeping.

St. Louis area medical professionals are throwing their support behind a bill making its way through the Missouri legislature. The bill would help protect high school athletes from concussions.

Among other measures, the High School Sports Brain Injury Prevention Act would require student athletes to be cleared by a doctor before returning to play or practice.

This article first appeared in the St. Louis Beacon: June 17, 2008 - Pat Millstone of University City has followed reports of Sen. Ted Kennedy's brain tumor and surgery with more than passing interest.

If anyone can relate to what Kennedy and his family is going through, it's Millstone.

Her husband, Jim Millstone, a former senior assistant managing editor of the St. Louis Post-Dispatch, died of a brain tumor in 1992. In the two years following surgery to remove the tumor, Pat Millstone watched her husband deteriorate in mind, body and spirit.

This article first appeared in the St. Louis Beacon: June 12, 2008 - Suzy Esstman's initial encounter with her brain tumor disease was less swift and dramatic than Sen. Kennedy's. In the summer and fall of 2003, she began to forget words.

Suzy's friends initially wrote it off to stress. After all, she and her husband, Don, of Chesterfield, were caught up in planning their son Andrew's bar mitzvah. And all the while Suzy was keeping up her dizzying volunteer schedule serving on projects, events and steering committees.
