Drug found to trigger the ‘energy balance’ system for appetite suppression
Penn researchers show how the FDA-approved drug liraglutide interacts with a distinct set of neurons in the brain’s “energy balance” system to suppress appetite.
Schizophrenic no more: Two subcategories in the brain redefine a blanket diagnosis
In a study of more than 300 patients from three continents, a second type of schizophrenia was discovered by observing brain matter that looks healthy, but with increased volumes of gray matter in the basal ganglia.
Machine learning identifies personalized brain networks in children
A Penn study shows variability among children’s neural anatomy which may inform personalized treatments for psychiatric disorders.
Lab-grown brain organoids, rapidly deployed, can fight glioblastomas
Glioblastoma organoids grown from patients’ own glioblastoma tissue can be used to investigate personalized treatment approaches in time-sensitive cases.
Surprise to some parents, adolescent brains ARE wired for self-control
A Penn study shows developing brain networks support cognition in youth, from decision-making and self-control to complex thought.
An Alzheimer’s research pioneer, right here at Penn
Virginia Man-Yee Lee, a professor and researcher at the Perelman School of Medicine, is the 2020 recipient of a Breakthrough Prize in Life Sciences, earning $3 million for her innovative, inspiring work that could one day cure various neurodegenerative diseases.
Justified and unjustified movie violence evoke different brain responses
In a new study, researchers at Penn find that scenes of unjustified and justified violence in movies activate different parts of the adolescent brain.
How does opioid exposure affect brain development in young children?
That’s the question Allyson Mackey and Dylan Tisdall hope to answer, through a new grant from an NIH initiative focused on addiction research.
Memory recall and spatial navigation elicit similar electrical activity in brain
Penn neuroscientists show for the first time that low-frequency oscillations called theta waves appear in both cases, a finding that could eventually help diminish memory loss.
The science of sensations
To confront the ills of the opioid epidemic, scientists must develop a fundamental understanding of the biology of pain. Biologist Ishmail Abdus-Saboor’s work is setting the stage for screening alternative drugs and uncovering new pathways that an opioid-alternative could target.
