Obama proposes $100M for brain mapping project

April 02, 2013, Associated Press
WASHINGTON - President Barack Obama on Tuesday proposed an effort to map the brain's activity in unprecedented detail, as a step toward finding better ways to treat such conditions as Alzheimer's, autism, stroke and traumatic brain injuries.
He asked Congress to spend $100 million next year to start a project that will explore details of the brain, which contains 100 billion cells and trillions of connections.
That's a relatively small investment for the federal government - less than a fifth of what NASA spends every year just to study the sun - but it's too early to determine how Congress will react.
Obama said the so-called BRAIN Initiative could create jobs, and told scientists gathered in the White House's East Room that the research has the potential to improve the lives of billions of people worldwide.
"As humans we can identify galaxies light-years away," Obama said. "We can study particles smaller than an atom, but we still haven't unlocked the mystery of the three pounds of matter that sits between our ears."
Scientists unconnected to the project praised the idea.
BRAIN stands for Brain Research through Advancing Innovative Neurotechnologies. The idea, which Obama first proposed in his State of the Union address, would require the development of new technology that can record the electrical activity of individual cells and complex neural circuits in the brain "at the speed of thought," the White House said.
Obama wants the initial $100 million investment to support research at the National Institutes of Health, the Defense Advanced Research Projects Agency and the National Science Foundation. He also wants private companies, universities and philanthropists to partner with the federal agencies in support of the research. And he wants a study of the ethical, legal and societal implications of the research.
The goals of the work are unclear at this point. A working group at NIH, co-chaired by Cornelia "Cori" Bargmann of The Rockefeller University and William Newsome of Stanford University, would work on defining the goals and develop a multi-year plan to achieve them that included cost estimates.
The $100 million request is "a pretty good start for getting this project off the ground," Dr. Francis Collins, director of the National Institutes of Health told reporters in a conference call. While the ultimate goal applies to the human brain, some work will be done in simpler systems of the brains of animals like worms, flies and mice, he said.
Collins said new understandings about how the brain works may also provide leads for developing better computers.
Brain scientists unconnected with the project were enthusiastic.
"This is spectacular," said David Fitzpatrick, scientific director and CEO of the Max Planck Florida Institute for Neuroscience in Jupiter, Fla., which focuses on studying neural circuits and structures.
While current brain-scanning technologies can reveal the average activity of large populations of brain cells, the new project is aimed at tracking activity down to the individual cell and the tiny details of cell connections, he said. It's "an entirely different scale," he said, and one that can pay off someday in treatments for a long list of neurological and psychiatric disorders including schizophrenia, Parkinson's, depression, epilepsy and autism.
"Ultimately, you can't fix it if you don't know how it works," he said. "We need this fundamental understanding of neuronal circuits, their structure, their function and their development in order to make progress on these disorders."
"This investment in fundamental brain science is going to pay off immensely in the future," Fitzpatrick said.
Richard Frackowiak, a co-director of Europe's Human Brain Project, which is funded by the European Commission, said he was delighted by the announcement.
"From our point of view as scientists we can only applaud and say we will collaborate as much as possible," he said. "The opportunities for a massive worldwide collaborative effort to solve the problem of neurodegeneration and psychiatric disease will ... really become absolutely feasible," he said. "We need that."

Brain Scans Can Display Mental Models of Others

Brain Scans Can Display Mental Models of Others

Fascinating new research discovers it is possible to tell who a person is thinking about by analyzing images of his or her brain. Neuroscientists f rom Cornell University discovered that advanced imaging techniques can display the unique patterns of brain activation that occur when we think of others. “When we looked at our data, we were shocked that we could successf ully decode who our participants were thinking about based on their brain activity,” said Nathan Spreng, Ph.D., assistant prof essor of human development in Cornell’s College of Human Ecology. Experts say that while everyone agrees that understanding and predicting the behavior of others is a key to managing lif e circumstances, little is known about how the brain actually models the enduring personality traits that may drive others’ behavior. The ability to predict behaviors helps us anticipate how someone will act in a situation that may not have happened bef ore. In an ef f ort to learn more about this innate ability, researchers asked 19 young adults to learn about the personalities of f our people who dif f ered on key personality traits. Participants were given dif f erent scenarios (i.e. sitting on a bus when an elderly person gets on and there are no seats) and asked to imagine how a specif ied person would respond. During the task, their brains were scanned using f unctional magnetic resonance imaging (f MRI), which measures brain activity by detecting changes in blood f low.
Investigators f ound that dif f erent patterns of brain activity in the medial pref rontal cortex (mPFC) were associated with each of the f our dif f erent personalities. In other words, which person was being imagined could be accurately identif ied based solely on the brain activation pattern.
The results suggest that the brain codes the personality traits of others in distinct brain regions and this inf ormation is integrated in the medial pref rontal cortex (mPFC) to produce an overall personality model used to plan social interactions, the authors say. “Prior research has implicated the anterior mPFC in social cognition disorders such as autism and our results suggest people with such disorders may have an inability to build accurate personality models,” said Spreng. “If f urther research bears this out, we may ultimately be able to identif y specif ic brain activation biomarkers not only f or diagnosing such diseases, but f or monitoring the ef f ects of intervention.
