The antipsychotic drugs that are increasingly being used to treat bipolar disorder, autism and other mental disorders in children may come with an increased risk of diabetes, a new study suggests. Previous research has linked the so-called second-generation antipsychotics to an increased risk of diabetes in adults. And there's been some evidence that the drugs can cause weight gain in children.
The new findings, published in the Journal of Pediatrics, add to concerns that the medications may ultimately lead to diabetes in some kids. And it's the growing use of the drugs in kids—particularly for conditions in which the benefit is unclear—that makes the potential diabetes risk concerning, according to Dr. Jonathan Mink, chief of child neurology at the University of Rochester Medical Center in New York.
These medications can be very helpful in certain settings,said Mink, who is also part of a pediatric advisory panel to the U.S. Food and Drug Administration. In September, the panel recommended that the agency keep monitoring the risks of weight gain and diabetes in children on antipsychotics.

The human brain is bombarded with a cacophony of information from the eyes, ears, nose, mouth and skin. Now a team of scientists at the University of Rochester, Washington University in St. Louis, and Baylor College of Medicine has unraveled how the brain manages to process those complex, rapidly changing, and often conflicting sensory signals to make sense of our world.
The study, published online Nov. 20 in Nature Neuroscience, represents the first direct evidence of how the brain combines multiple sources of sensory information to form as accurate a perception as possible of its environment, the researchers report.
The discovery may eventually lead to new therapies for people with Alzheimer's disease and other disorders that impair a person's sense of self-motion, says study coauthor Greg DeAngelis, professor and chair of Brain and Cognitive Sciences at the University of Rochester. This deeper understanding of how brain circuits combine different sensory cues could also help scientists and engineers to design more sophisticated artificial nervous systems such as those used in robots, he adds.
Adding randomly moving dots, or visual "noise," makes the visual motion cues much harder for your brain to interpret, until the noise is removed toward the end of the video. Help us caption & translate this video! http://amara.org/v/CHAC/

The brains of autistic children have far more neurons in the prefrontal cortex than the brains of kids without autism, finds a new study that could advance research into the disorder.
For the first time, we have the potential to understand why autism gets started,said study author Eric Courchesne, a professor of neurosciences at the University of California, San Diego School of Medicine and director of the Autism Center of Excellence.
The prefrontal cortex is key to complex thoughts and behaviors, including language, social behavior and decision-making. The dorsolateral prefrontal cortex is closely linked with
executive function,including planning, reasoning and
very high level cognition,said Lizabeth Romanski, an associate professor of Neurobiology & Anatomy at the University of Rochester Medical Center, who was not involved with the research. The mesial prefrontal cortex is thought to be important to social and other behavior and emotions.

As it turns out, keeping pace in ever-more-electronic world is no small feat for the aging brain. That's because our mental circuitry – the most frequently used neuron pathways, like well-traveled roads – tends to
crystallizeinto a series of expressways over time. But that doesn't mean paving new paths (by, say, learning in middle age) is a lost cause – it just demands special learning techniques and a little more patience.
That's heartening news for adults who are headed back to school, shifting careers in later life, or simply want to be lifelong learners, says neuropsychologist Dr. Mark Mapstone. In the clip below, he sheds more light on our amazing (and aging) brains.

Ask any number of men what they think their odds of having a stroke are, and you might find many of them believe stroke is frighteningly unpredictable and can attack like a bolt from the blue – without warning, trailing death and disability in its wake.
That idea is dangerously wrong. The truth is that a stroke is the bullet at the end of a very long barrel and there is a lot you can do to dodge it.
The path to stroke can be started by heart disease – especially if you have an irregular heartbeat. It also can be started by arterial disease – especially if there is a build-up of plaque in the arteries of the neck. The chain of events that begins with cardiovascular disease and ends in stroke can take years, or even decades to evolve. You probably will not know that it is happening.

Searching frantically for misplaced car keys. Fumbling for the name of a new acquaintance. Providing an accurate eye-witness testimony. Treasuring past moments with a loved one lost. What, exactly, is this thing we call “memory”? How do our brains manage to process, store and recall so much sensory footage – even lifeless data, like phone numbers – almost reflexively?
Neuropsychologist Dr. Mark Mapstone co-directs URMC's memory care clinic, which features a team of neurologists, psychiatrists, a geriatrician, a neuropsychologist, a psychometrician (expert in measuring psychological function), a social worker and a nurse practitioner. He weighs in on these and other burning questions in the clip below.
What, exactly, is this thing we call "memory?" How do our brains manage to process, store and recall so much sensory footage -- even lifeless data, like phone numbers -- almost reflexively? And perhaps the more urgent question is this: Could the torrent of modern technology, with its so many "memory crutches" -- GPS navigators, calculators, search engines, smart phones -- be eroding our brain's natural capacity to remember? In this clip, neuropsychologist Dr. Mark Mapstone weighs in.

Staring at a computer screen wasn't exactly what Nicole Newhouse envisioned for her career. It didn't take long for her to find a subject that sparked a new passion. Newhouse said,
You have children that are dying. Point blank, you have children that are dying.Newhouse is enrolling patients in the first controlled clinical trial for batten disease.
We don't have a cure right now. We can't tell parents 'you take this and your child's going to be ok,said Newhouse.
Batten disease is a neurological disorder that usually appears in children ages four to eight years old. Early symptoms of the disease include sudden vision problems. That's quickly followed by a loss of motor skills, mental impairment and eventually death.
Try to imagine what it's like for the parents to watch their child basically dying before their eyes. Over many years, it's the kind of thing that as a physician you see and think you know I want to do something to help,said Dr. Jonathan Mink, professor in the departments of Neurology, Neurobiology & Anatomy, Pediatrics, and Brain and Cognitive Sciences at the University of Rochster Medical Center.

More than a dozen children with so-called
bubble boydisease are alive and well, with functioning immune systems, nine years after undergoing gene therapy to correct their disorder, researchers report. Most of the patients attend school with other children, something that probably would have been fatal without treatment.
With gene therapy, clinicians remove the patient's own bone marrow, isolate the stem cells, correct the gene and reinsert it into the patient, explained William J. Bowers, associate professor of neurology at the University of Rochester Medical Center in Rochester, N.Y.
This field came on with huge promise, then hit a few bumps and now . . . we're starting to see more and more of these successes,added Bowers.

Brain areas involved in making decisions about rewards are highlighted.
A Rochester neuroscientist whose laboratory research has already helped patients has received a prestigious award to explore new opportunities to help people with conditions like schizophrenia, depression, obsessive-compulsive disorder, and addiction.
Suzanne Haber, Ph.D., professor of Pharmacology and Physiology at the University of Rochester Medical Center, has received a Distinguished Investigator Grant from the Brain and Behavior Research Foundation. She is one of 15 scholars nationwide to receive the award, also known as a NARSAD award (the foundation was previously known as the National Alliance for Research in Schizophrenia and Depression). Each recipient receives $100,000 toward new research aimed at alleviating the suffering caused by mental illness.
Haber is a world leader uncovering and understanding the wiring in a highly sophisticated part of the brain known as the prefrontal cortex – the part of the brain involved in decision-making that involves reward and potential risk. The prefrontal cortex is what prompts us to forego a box of cookies for breakfast, for instance, so we can reach our long-term weight-loss goal, or that helps keep a student studying late at night in the quest to obtain her college degree, instead of partying with friends.

Scientists have come up with new insight into the brain processes that cause an age-old illusion, first documented by Aristotle. The illusion is called the Motion Aftereffect by today's scientists, but why does it happen, though? Is it because we are consciously aware that the background is moving in one direction, causing our brains to shift their frame of reference so that we can ignore this motion? Or is it an automatic, subconscious response?
Davis Glasser, a doctoral student in the University of Rochester's Department of Brain and Cognitive Sciences thinks he has found the answer. The results of a study done by Glasser, along with his advisor, Professor Duje Tadin, and colleagues James Tsui and Christopher Pack of the Montreal Neurological Institute, will be published this week in the journal Proceedings of the National Academy of Sciences (PNAS). In their paper, the scientists show that humans experience the Motion Aftereffect even if the motion that they see in the background is so brief that they can't even tell whether it is heading to the right or the left.

Two proteins that are abnormally modified in the brains of patients with Alzheimer disease collude, resulting in ill effects on the crucial energy centers of brain cells, according to new findings published online in Neurobiology of Aging. The research raises the possibility that pathological forms of two proteins, amyloid beta and tau, which make up the pathological hallmarks of the brains of Alzheimer patients – plaques and tangles – may work in tandem to decrease the survival of brain cells.
The idea that amyloid beta and tau may work together to cause mischief in the brain has been an evolving theme among scientists for a number of years,said Gail Johnson, Ph.D., professor of Anesthesiology and the corresponding author of the paper.
The precise relationship between the two pathologies is unclear, but there may be a synergy between the two when it comes to their effects on mitochondria in Alzheimer disease.

A mother's iron deficiency early in pregnancy may have a profound and long-lasting effect on the brain development of the child, even if the lack of iron is not enough to cause severe anemia, according to a University of Rochester Medical Center study published in the scientific journal PLoS One.
What convinced us to conduct the present study were our preliminary data suggesting that cells involved in building the embryonic brain during the first trimester were most sensitive to low iron levels,said Margot Mayer-Proschel, Ph.D., the lead researcher and an associate professor of Biomedical Genetics at URMC.
Co-author Anne Luebke, Ph.D., an associate professor of Biomedical Engineering and Neurobiology & Anatomy at UR, suggested and directed the use of ABR testing, which can detect the speed of information moving from the ear to the brain.

It is with deep personal sadness that I inform the Department of Neurobiology and Anatomy, as well as the broader neuroscience and UR community, that our own Bob Doty passed away on Friday, January 14th, 2011. Bob had been a monumental presence in our midst for decades, and was arguably our most eminent neuroscientist on campus (read an autobiographical SFN publication written by Dr. Doty). A friend to many, and admired by all who knew him, we will miss his remarkable and steadfast presence among us, as well as his routine appearance at seminars--always with that extraordinary flair for insightful questions and comments. It was truly fitting that our last departmental winter banquet was held in honor and celebration of Bob near his 90th birthday. At the wishes of Bob's family, plans for a memorial will be considered in the spring.

Dr. Gary Paige, Chair and Professor of Neurobiology & Anatomy, was a featured panelist on the web-based TV show, Second Opinion. The basis of this show was dizziness and vertigo of which Dr. Paige is an expert. Dr. Paige also runs the Balance Disorders and Dizziness Clinic at the University of Rochester.
When you are dizzy, you may feel lightheaded or lose your balance. If you feel that the room is spinning, you have vertigo. A sudden drop in blood pressure or being dehydrated can make you dizzy. Many people feel lightheaded if they get up too quickly from sitting or lying down. For

Structure of a Synapse
New research from the Majewska Lab at University of Rochester Medical Center is revealing even more reasons to stand up and applaud the microglia. It turns out that microglia serve more than immune functions. They are essential to learning and memory. This research suggests that a lot of what is going on in that synaptic gap is engineered by the microglia.
The research team, led by Ania Majewska, Ph.D., Assistant Professor in the department of Neurobiology & Anatomy, used two imaging techniques to study the microglia in the animals' brains during these various stages. When the lights were off, microglia contacted more synapses, were more likely to reach toward a particular type of synapse, tended to be larger, and were more likely to destroy a synapse. When the lights came back on, most of those activities reversed.
The finding that activity among microglia changed in response to visual inputs was, in itself, surprising.
Just the fact that microglia can sense that something has changed in the environment is a novel idea,says Majewska.
