‘Light-to-moderate’ drinking may carry risks to the brain, new study says Penn In the News The Hill ‘Light-to-moderate’ drinking may carry risks to the brain, new study says Henry Kranzler of the Perelman School of Medicine and Gideon Nave of the Wharton School spoke about their research on alcohol’s effects on the brain. “Although the National Institute on Alcohol Abuse and Alcoholism recommends that women consume an average of no more than one drink per day, recommended limits for men are twice that, an amount that exceeds the consumption level associated in the study with decreased brain volume,” he said. Why are alcohol- and drug-related deaths rising in the U.S. and not elsewhere? Why are alcohol- and drug-related deaths rising in the U.S. and not elsewhere? With insights from anthropology and neuroscience, Penn researchers Michael Platt and Peter Sterling find that, in comparison, 16 other wealthy nations offer communal assistance at every life stage, support that protects individuals and families long term.

Natural landscapes were transformed into binary images, ones made of black and white pixels, that were decomposed into different textures defined by specific statistics.

Can a digital reality be jacked directly into your brain? Penn In the News Wired Can a digital reality be jacked directly into your brain? Researchers led by Daniel Yoshor of the Perelman School of Medicine are developing better electrode arrays, which are used to induce neural activity. Current arrays approved for human use are bulky and contain around 1,000 electrodes, whereas the arrays Yoshor and colleagues are working on would have 64,000 electrodes, and eventually 1,000,000 electrodes.

In the brain’s cerebellum, a new target for suppressing hunger Signals between the brain and stomach help animals decide when and how much to eat. A research collaboration involving Penn neuroscientists has uncovered a sensor for fullness in an area of the brain never before associated with satiation: the cerebellum. (Image: Courtesy of the Betley laboratory) In the brain’s cerebellum, a new target for suppressing hunger A research team led by J. Nicholas Betley in the School of Arts & Sciences has identified an entirely new way the brain signals fullness after eating. The findings offer a novel target for therapies that could dramatically curb overeating. Who was the man with the uneven gait?

Duffin collaborated with Geoffrey Aguirre of the Perelman School of Medicine and Geoffrey Noble, a former PSOM resident, to learn more about a group of neurological patients photographed in the Victorian era. A new model for how the brain perceives unique odors A new study from the lab of Vijay Balasubramanian describes a statistical model for how the olfactory system discerns unique odors. This work provides a starting point for generating new hypotheses and conducting experiments that can help researchers better understand this complex, crucial area of the brain. A new model for how the brain perceives unique odors Using statistical physics and insights from biology, this research can help inform new hypotheses and experiments towards understanding the olfactory system, a complex and crucial pathway of the brain.
