Targeting the 'good' arm after stroke leads to better motor skills

Traditional stroke rehabilitation therapy focuses on restoring strength and movement to the more impaired side of the body, but a new randomized clinical trial has revealed that targeted therapy for the less-impaired arm significantly improved movement and control for stroke survivors. The trial, led by researchers from Penn State and the University of Southern California (USC), compared the new approach to the standard best-practice therapy currently in use.

Eberly College introduces Science Matters: Spotlight Sessions outreach events

The Penn State Eberly College of Science is introducing a new series of outreach events — titled Science Matters: Spotlight Sessions — to provide a unique opportunity for the community to engage directly with the brilliant minds working on the front lines of discovery to create positive, real-world impact.

When dreams turn dark: Neuroscientists to study nightmares and mental health

Dreams, and likely nightmares, are experienced universally across humans and animals, but neuroscientists still do not know why. Now, with a three-year, $1.2 million grant from the W.M. Keck Foundation, an interdisciplinary team of researchers at Penn State will study the underlying mechanisms of nightmares and their relationship with anxiety-related mental health disorders, such as post-traumatic stress disorder (PTSD).

The breadth of the brain

Researchers in the Penn State Neuroscience Institute study the brain’s many aspects in a variety of ways, with implications from mental health to aging and disease.

How a genetic tug-of-war decides the fate of a honey bee

Despite having identical genetic instructions, female honey bee larvae can develop into either long-lived reproductive queens or short-lived sterile workers who help rear their sisters rather than laying their own eggs. Now, an interdisciplinary team led by researchers at Penn State has uncovered the molecular mechanisms that control how the conflict between genes inherited from the father and the mother determine the larva’s fate.
