Slower growth in working memory linked to teen driving crashes
Adolescent drivers have the highest rate of vehicle crashes. Variability in working memory development might be a factor, and researchers at the Annenberg Public Policy Center tested the association between crashes and differential working memory development.
Researcher Virginia M.Y. Lee receives $3 million Breakthrough Prize
The Breakthrough Prize award recognizes Lee’s work studying underlying mechanisms of neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, and other dementias.
No evidence that testosterone reduces cognitive empathy
In the largest study of its kind, researchers found that testosterone administration did not affect cognitive empathy, a measure of the ability to recognize another’s feelings and motivations. The finding calls into question the theory that the symptoms of autism are caused by a hyper-masculinized brain.
Using a matching game to study the language of conversations
Penn undergrads Lilian Zhang and Kassidy Houston, and University of Chicago student Benjamin Stallworth, interned in the lab of cognitive psychologist Delphine Dahan doing work to better understand what subconsciously happens when people converse.
Could NFL players’ performance after a concussion mask the dangers?
A new study shows NFL players return to the field quickly and with no dip in their stats, but this may come at a cost.
Five insights into how the brain works
As the Center for Neuroscience & Society celebrates 10 years, founding director Martha Farah reflects on the array of research from its faculty, on subjects from brain games to aggression.
The brain’s amyloid buildup is not a powerful indicator of Alzheimer’s disease
Researchers find fluorodeoxyglucose (FDG) PET, which measures the brain’s glucose consumption as a marker of neural activity, is a better indicator of cognitive performance when compared to PET scans that detect amyloid proteins.
When a fix for one vision problem causes another
Aging diminishes the ability of the eyes to focus up close. New Penn research reports that monovision, a common prescription lens correction to mitigate this issue, can cause dramatic misperceptions of depth and 3D direction for objects in motion.
Brain matter altered in U.S. personnel who developed neurological symptoms in Cuba
Images reveal key brain differences, particularly in the cerebellum, between impacted patients and healthy individuals, which may underlie clinical findings previously reported by the Penn team.
Taking out the protein garbage becomes more difficult as neurons age
As cells age, their ability to remove damaged proteins and structures declines, which could be a risk factor for neurodegenerative brain diseases.
