From intro class to a Science publication in three years

Holly Gildea didn’t come to Brown expecting to publish in one of the world’s top scientific journals, or even to study neuroscience, but by discovering and pursuing her passion, she’s achieved an auspicious start to a research career.

PROVIDENCE, R.I. [Brown University] — Growing up in Barrington, R.I., senior Holly Gildea had a sense that Brown University could be the college for her, and when she visited campus for “A Day on College Hill” in 2012, she became sure. (more…)

Mobile games used for psychology experiments

Initial findings from one of the largest cognitive science experiments ever conducted have shown that mobile games can be used to reliably address psychology questions, paving the way to a better understanding of how cognitive function differs across populations.

With its first comprehensive set of results published today, the Great Brain Experiment, a free mobile app run by neuroscientists at the Wellcome Trust Centre for Neuroimaging at UCL, uses ‘gamified’ neuroscience experiments to address scientific questions on a scale that would not be possible using traditional approaches. The app investigates memory, impulsivity, risk-taking and happiness. By playing the games, anyone can anonymously compare their abilities to the wider population and contribute to real scientific research. More than 60,000 people have taken part so far. (more…)

Free will seems a matter of mind, not soul

A new study tested whether people believe free will arises from a metaphysical basis or mental capacity. Even though most respondents said they believed humans to have souls, they judged free will and assigned blame for transgressions based on pragmatic considerations — such as whether the actor in question had the capacity to make an intentional and independent choice.

PROVIDENCE, R.I. [Brown University] — Across the board, even if they believed in the concept of a soul, people in a new study ascribed free will based on down-to-Earth criteria: Did the actor in question have the capacity to make an intentional and independent choice? The study suggests that while grand metaphysical views of the universe remain common, they have little to do with how people assess each other’s behavior. (more…)

The Universe in the Middle of Nowhere

The UA’s Chris Impey has taught cosmology to Tibetan Buddhist monastics in remote parts of India each summer for the past five years. With a grant from the John Templeton Foundation, he detailed his experiences in a book, “Humble Before the Void,” which likely will publish in 2014.

Chris Impey thinks back to the time he spent living on the edge of Tibetan Buddhist monasteries, teaching modern cosmology to Buddhist monastics in India: “On a typical day, they would be up at 5 a.m. and have prayed for a few hours or done meditation before you even see them. And their attention is just as good at the end of a long day as at the beginning.” (more…)

Tests Conducted on Israel’s Ariel Sharon Reveal Significant Brain Activity

Scientists use new methods developed by UCLA’s Martin Monti

A team of American and Israeli brain scientists tested former Israeli Prime Minister Ariel Sharon to assess his brain responses, using functional magnetic resonance imaging (fMRI). Surprisingly, Sharon showed significant brain activity.

The team consisted of Martin Monti, an assistant professor of psychology and neurosurgery at UCLA, professors Alon Friedman, Galia Avidan and Tzvi Ganel of the Zlotowski Center for Neuroscience at Israel’s Ben-Gurion University of the Negev, and Dr. Ilan Shelef, head of medical imaging at Israel’s Soroka University Medical Center.

University of Toronto Study Demonstrates Impact of Adversity on Early Life Development

Study part of growing body of knowledge surrounding gene-environment interplay

TORONTO, ON – It is time to put the nature versus nurture debate to rest and embrace growing evidence that it is the interaction between biology and environment in early life that influences human development, according to a series of studies recently published in a special edition of the Proceedings of the National Academy of Sciences (PNAS).

“Biologists used to think that our differences are pre-programmed in our genes, while psychologists argued that babies are born with a blank slate and their experience writes on it to shape them into the adults they become. Instead, the important question to be asking is, ‘How is our experience in early life getting embedded in our biology?’” says University of Toronto behavioural geneticist Marla Sokolowski. She is co-editor of the PNAS special edition titled “Biological Embedding of Early Social Adversity: From Fruit Flies to Kindergarteners” along with professors Tom Boyce (University of British Columbia) and Gene Robinson (University of Illinois).

Yoga Reduces Stress; Now It’s Known Why

UCLA study helps caregivers of people with dementia

Six months ago, researchers at UCLA published a study that showed using a specific type of yoga to engage in a brief, simple daily meditation reduced the stress levels of people who care for those stricken by Alzheimer’s and dementia. Now they know why.

As previously reported, practicing a certain form of chanting yogic meditation for just 12 minutes daily for eight weeks led to a reduction in the biological mechanisms responsible for an increase in the immune system’s inflammation response. Inflammation, if constantly activated, can contribute to a multitude of chronic health problems. (more…)

UCLA Researchers Map Damaged Connections in Phineas Gage’s Brain

Famous 1848 case of man who survived a terrible accident has modern parallel

Poor Phineas Gage. In 1848, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head. As reported at the time, the rod was later found, “smeared with blood and brains.”

Miraculously, Gage lived, becoming the most famous case in the history of neuroscience — not only because he survived a horrific accident that led to the destruction of much of his left frontal lobe but also because of the injury’s reported effects on his personality and behavior, which were said to be profound. Gage went from being an affable 25-year-old to one that was fitful, irreverent and profane. His friends and acquaintances said he was “no longer Gage.” (more…)
