Scientists are still trying to piece together why our hearing goes downhill with age, with the goal of trying to slow it or even reverse it. When it comes to the cocktail party problem, the dimmer switch is a piece of that story, though it's not clear just how big a factor.
I think it's a significant player,said Robert Frisina of the University of Rochester in New York, who is studying it. Frisina and colleagues published evidence in 2002 that the dimmer switch effectiveness declines with age. The drop-off showed up in middle-aged people (ages 38 to 52) and was even worse in people past age 62.

How our brain controls our movements is a bit more complex and varied than scientists have previously recognized, according to research recently published in Science by a team of scientists and physicians at the University of Rochester Medical Center.
The team led by neurologist Marc Schieber, M.D., Ph.D., professor of Neurology and of Neurobiology & Anatomy, showed that at least occasionally, the brain is able to bypass the usual route of nerve fibers it uses for controlling hand and finger movements, using an alternate route to send its signals. Such flexibility in controlling movement has been suspected but not actually shown before.

The research by neuroscientists at the URMC was presented at the annual meeting of the Society for Neuroscience in San Diego Nov. 3-7. The work was highlighted as part of a press conference on potential environmental influences on Alzheimer's disease.
The team found that copper damages a molecule known as LRP (low-density lipoprotein receptor-related protein), a molecule that acts like an escort service in the brain, shuttling amyloid-beta out of the brain and into the body. The molecule's role in Alzheimer's was revealed more than a decade ago by another author of the work, Berislav Zlokovic, M.D., Ph.D., professor of Neurosurgery and Neurology and director of the Frank P. Smith Laboratory for Neuroscience and Neurosurgery Research. Zlokovic is widely recognized for demonstrating that blood vessels, blood flow, and the blood-brain barrier are central to the development of Alzheimer's disease.

Scientists at the University of Rochester Medical Center have received $1.37 million to continue their work looking at some of the earliest events that occur at the start of Alzheimer's disease – a condition that now generally goes undetected until the death of key brain cells has been underway for decades.
The team led by William Bowers, Ph.D., associate professor of Neurology and a scientist in the Center for Neural Development and Disease, is focusing on the role of inflammation in the evolution of the disease. Just as rheumatoid arthritis can ravage the body's joints because of the inflammation it causes, scientists are realizing that the same thing happens to the brain in patients with Alzheimer's disease. The brain can be under assault for decades as the body attempts to fend off some perceived threat.

Scientists are trying a plumber's approach to rid the brain of the amyloid buildup that plagues Alzheimer's patients: Simply drain the toxic protein away.
That's the method outlined in a paper published online August 12th by Nature Medicine. A team of scientists from the University of Rochester Medical Center, led by neuroscientist Berislav Zlokovic, M.D., Ph.D., show how the body's natural way of ridding the body of the substance is flawed in people with the disease. Then the team demonstrated an experimental method in mice to fix the process, dramatically reducing the levels of the toxic protein in the brain and halting symptoms. The team is now working on developing a version of the protein that could be tested in people with the disease.

As part of a five-year, $3.5 million grant from the National Institutes of Health (NIH), researchers will look at whether a breakthrough therapy for Parkinson's disease can also treat the worst cases of obsessive compulsive disorder (OCD). A research team led out of the University of Rochester Medical Center will measure whether Deep Brain Stimulation (DBS) can reduce the rampant anxiety that keeps some OCD patients homebound.
DBS is one of the most promising areas of OCD research because early studies show that it may help many within the approximately 20 percent of OCD patients for whom neither psychological nor drug therapy works,said Suzanne Haber, Ph.D., a professor within the Department of Pharmacology and Physiology at the University of Rochester School of Medicine and Dentistry.
Some patients have been able to venture out to work and school for the first time with DBS,said Haber, who is lead investigator for the grant.

A tiny section of the brain that is ravaged by Alzheimer's disease is more important for our ability to orient ourselves than scientists have long thought, helping to explain why people with the disease become lost so easily. The findings by neuroscientists at the University of Rochester Medical Center are reported in the March 29 issue of Science.
Neurologist Charles Duffy, M.D., Ph.D., previously discovered that a small section of brain tissue slightly above and behind the ear - known as the medial superior temporal area (MST) - acts much like a compass, instantly updating your mental image of your body's movements through space. In new research, Duffy and graduate student Michael Froehler show that the MST acts not only as a compass but also as a sort of biological global positioning system, providing a mental map to help us understand exactly where we are in the world and how we got there.

Doctors have added to the evidence that patients with Alzheimer's disease lose their way not simply because their memory is failing but because they are subject to a unique form of brain damage that causes symptoms doctors call "motion blindness." Some of the new data comes from driving tests of a small number of patients, where researchers have linked the condition to the loss of one specific driving skill: the ability to stay in one's lane while driving.
While it's obvious that people with Alzheimer's disease are losing their memory, that's only part of the reason why they become lost,says neurologist Charles Duffy, M.D., Ph.D., who leads the research team at the University of Rochester Medical Center.
These patients also lose their ability to perceive their own motion. That's ultimately what puts them at much greater risk than others of becoming lost.
