Maryam Shanechi, Dean’s Professor of Electrical and Computer Engineering and founding director of the USC Center for Neurotechnology, and her team have developed a new machine learning method that reveals surprisingly consistent intrinsic brain patterns across different subjects by disentangling these patterns from the effect of visual inputs.The work has been published in the Proceedings of the National Academy of Sciences (PNAS). When performing various everyday movement behaviors, such as reaching for a book, our brain has to take in information, often in the form of visual input — for example, seeing where the book is. Our brain then has to process ...

Every year, around 50,000 people in the United States experience cardiogenic shock — a life-threatening condition, usually caused by a severe heart attack, in which the heart can’t pump enough blood for the body’s needs. Many of these patients end up receiving help from a mechanical pump that can temporarily help the heart pump blood until it recovers enough to function on its own. However, in nearly half of these patients, the extra help leads to an imbalance between the left and right ventricles, which can pose danger to the patient. In a ...

Chronic exposure of human skin to ultraviolet light causes premature aging, or photoaging. As the skin undergoes photoaging, type I collagen bundles, which are found in the dermis beneath the top layer of the skin and provide strength and support to skin, become fragmented. This leads to wrinkles, fragility and loss of support and elasticity.   “The best way to prevent damage to type I collagen by sunlight is to wear sunscreen consistently, daily if possible and particularly when spending time outdoors,” said Frank Wang, MD,  the William B. Taylor Endowed Professor of Clinical Dermatology at U-M Medical School.  Experts ...
