What a Fish's Brain Says, and Doesn't Say, About Yours

Researchers demonstrate a way to watch the brain activity of the tiny zebrafish in real time, a baby step toward the dream of mapping human brain activity.<p><b>To watch the entire human brain at work</b>—seeing it as an interconnected whole rather than a group of connected regions—is a scientist's dream. …

Depression stems from miscommunication between brain cells; Study challenges role of serotonin in depression

A new study suggests that depression results from a disturbance in the ability of brain cells to communicate with each other. The study indicates a …

Brain Injury Awareness Month: New Hope for the Brain-Injured Person

Did you know that 1.7 million people, including nearly 475,000 children, sustain a traumatic brain injury (TBI) in the United States each year?<p>This statistic comes from the Brain Injury Association of America, as well as this fact: 3.1 million individuals live with lifelong disability as a result …

Making new neurons in a living brain

Across most of our brain, the neurons that we’re born with are the ones we have throughout our lives. We make new ones in two small areas—the hippocampus, involved in memory and navigation, and (briefly in) the olfactory bulb, responsible for smell. Elsewhere, we’re stuck with the same old supply. …

This Is Your Brain on Nature

A portable EEG can tell whether you're on a busy street or in a park.<p>Going for a walk (or a run or a bike ride) in the forest feels different from going for a walk on the shoulder of a freeway or through the streets of downtown Tokyo. And it doesn't just <b>feel</b> different -- the different scenarios …

<i>15 years after she lost the ability to move her body, Cathy Hutchinson is learning how to use her brain to control a robotic arm.</i><p>Today scientists announced in the journal <i>Nature</i> the results of a landmark experiment in which paralyzed subjects were able to control a robotic arm using only their …

Brain Protein Linked To Down Syndrome May Be Cause Of Learning & Memory Problems

It's well-established that Down syndrome results when a person is born with an extra 21st chromosome, but so far, scientists haven't pinned down what causes the condition's symptoms.<p>New research, however, brings us one step closer to understanding Down Syndrome's molecular biology.<p>Researchers at …

Right Brain/Left Brain Thinking

Not unlike many media outlets, <i>The New York Times</i> recently reported about President Obama's call for "a multiyear research effort to produce an 'activity map' that would show in unprecedented detail the workings of the human brain."<p>George H.W.Bush made another presidential call for a study of the …

Somewhere Over The Brainbow: The Journey To Map the Human Brain

During the State of the Union, President Obama said the nation is about to embark on an ambitious project: to examine the human brain and create a road map to the trillions of connections that make it work.<p>"Every dollar we invested to map the human genome returned $140 to our economy — every …

Navigating the Brain Activity Map

President Obama's recent commitment to the Brain Activity Map (BAM) project has given neuroscientists worldwide reason to celebrate, but the business community has just as much to gain from the initiative. The ten-year grant furnishes researchers with $300M a year for at least ten years, …

BRAIN Initiative: A Bold Venture Into Brain Science

A top priority for science in the United States is the encouragement of high-risk, high-reward research, the kind that has the potential for transformational, rather than incremental, discoveries. In times of tight budgets, such research is typically underfunded and underappreciated, because it can …

The BRAIN Initiative: Ethical Challenges Ahead

When President Obama made his April 2 announcement about the BRAIN (Brain Research through Advancing Innovative Neurotechnologies) initiative, he hailed it as "the next great American project":<p>As humans, we can identify galaxies light years away, we can study particles smaller than an atom. But we …

Getting Better Views of Brains by Turning Them Invisible

In H. G. Wells’ The Invisible Man, the protagonist Griffin performs a mysterious procedure upon himself to become invisible. In Marvel’s Fantastic Four comics, it’s a dose of “cosmic rays” that gives the Invisible Woman her powers. And at Stanford University, it’s a technique called CLARITY that …
