Penn senior Max Wragan is one of 12 in the nation chosen to receive a George J. Mitchell Scholarship for postgraduate study in Ireland in 2022-2023. 

Penn senior Max Wragan named George J. Mitchell Scholar

Senior Max Wragan, a neuroscience major and chemistry minor, has been selected for a George J. Mitchell Scholarship, which covers one academic year of postgraduate studies in Ireland, including stipends for living and travel expenses.
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? Mystery medical photos come to life with discovery of long-lost Penn archives

Penn Archivists J.J. Ahern and J.M. 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.

Trump true believers have their reasons

Trump true believers have their reasons

Clifford Workman, a postdoctoral fellow in the Perelman School of Medicine, co-authored research about the neuroscience of morality. “People are motivated by shared social values that, when held with moral conviction, can serve as compelling mandates capable of facilitating support for ideological violence,” Workman and colleagues wrote.

A microscopic worm may shed light on how we perceive gravity

A microscopic worm may shed light on how we perceive gravity

C. elegans shares more than half of its genes with humans, allowing genetic studies to give insight into which genes are responsible for similar traits in humans, such as pinpointing molecular pathways responsible for gravitaxis, the ability to move in response to gravity.
