Forget right-brain or left-brain thinking. What may be more important from a gender standpoint is back-to-front or side-to-side thinking. A new study from the University of Pennsylvania used diffusion tensor imaging, a type of brain imaging that shows how brain cells are connected, to study young men and women. The team's maps of major information highways were noticeably different for the two genders. Men had more pathways that ran the length of each hemisphere, to parts within a hemisphere and across the cerebellum, which coordinates movement.

She was supposed to be on her way to a neon-lit chapel where an Elvis impersonator waited to officiate at her wedding. Instead, the 27-year-old woman sat in a thin hospital gown on an examining table in a cold emergency room, anxiously waiting for news. A week before, she had gone to see her primary physician. She had been dealing with a series of strange symptoms over the summer. A curious, maddening itch. Achy joints from time to time. Vicious headaches that she supposed were like migraines, although she had never had them before.

'Mom, how long has this been going on?" the woman asked as she helped her 75-year-old mother back into bed. The woman had never seen her mother so unsteady on her feet. She walked as if drunk. "My left side feels so weak. I even have a hard time feeling my leg on that side," the mother said. "It started last night. " The daughter was alarmed on hearing her mother's slurred speech and learning how long the symptoms had been present. Worried that her mother might have suffered a stroke, she called 911. The responding EMTs shared her concern and rushed the elderly woman to the hospital.

It's a scene that might be repeated dozens of times on Drexel University's campus today: A student, sitting at a table, eating pizza. But Annie Feng is different. The sophomore nibbles on a mini pizza while wearing a headband designed to measure her brain activity. And unlike many brain-imaging machines, this device can be used at a table. By monitoring the brains of people during meals, researchers hope to learn about the cognitive aspects of eating, and why some people stop at a single slice while others devour the pie. This portable device has sparked the interest of researchers worldwide.

QR Pharma is a five-year-old start-up company based in Berwyn, but the young firm has been able to connect with well-known people and groups as it seeks funding to make drugs to treat Alzheimer's and Parkinson's diseases. In 2012, QR Pharma got $468,000 from the Michael J. Fox Foundation for Parkinson's Research to explore a compound called Posiphen as a potential treatment for Parkinson's. This grant is for work that will be led by Robert Nussbaum of the University of California, San Francisco, and Jack T. Rogers, an associate professor of psychiatry at the genetics and aging research unit of Massachusetts General Hospital.

* FRONTLINE. LEAGUE OF DENIAL: THE NFL'S CONCUSSION CRISIS. 9 tonight, WHYY12. HALL OF FAMER Harry Carson has a 3-year-old grandson who won't be playing football if Carson has anything to say about it. "I've told his mom, my daughter, that he's not going to play football.

Getting injured is a tricky thing. I'm a month into running again after being forced to take three months off. I thought recovery would be easier when I was allowed to hit the road again. Not quite. "It's very rare, in my experience, that physical rehab and emotional rehab progress at the same pace," said Joel Fish, sports psychologist and director of the Center for Sports Psychology in Philadelphia. And that's true. After a month off my feet - after the novelty of riding a stationary bike and having more free time wore off - I was ready to get back out there.

William Acosta lies asleep on an operating table at Jefferson University Hospital. A surgeon is drilling a pen-sized hole into his skull. Curiously, the OR begins to smell like sawdust. Doctors then reduce his anesthesia, and Acosta, his brain still open, wakes up. Over the next five hours, Acosta, 56, of Glenside, will be both a patient and a collaborator in his own brain care. By staying awake, he will help surgeons find the part of his brain involved in Parkinson's disease.

CAN YOU believe it? Summer is gone and another school year is upon us! While many of us parents are scrambling to lock down new wardrobes, bus schedules and school supplies for our kids, there's one more thing we need to put on the table, literally: breakfast. Breakfast not only helps kids (and adults) maintain a healthy weight, it also gives schoolchildren a cognitive boost, increasing concentration, memory, test scores and even attendance. Countless studies have proved the importance of eating breakfast.

The NFL had considerable legal defenses in its fight with retired players over injuries caused by the violent collisions that are at the heart of the sport, not the least of those being a contract with the players that substantially restricts lawsuits. But in the face of public opinion, and the potential damage to its image, those defenses likely became much less important to the league. The prospect of slugging it out with the players in a multiyear litigation battle in which damaging information is disclosed and the public is regularly reminded of the sport's sometimes brutal impact on player health likely was a powerful incentive for the league to settle.
