Today, there is increasing exposure of individuals to a public audience. Television shows and the internet provide platforms for this and, at times, allow observing others' flaws and norm transgressions. Regardless of whether the person observed realizes their flaw or not, observers in the audience experience vicarious embarrassment.

CHICAGO – Subtle differences in brain anatomy among older individuals with normal cognitive skills may be able to predict both the risk of developing Alzheimer's disease in the following decade and how quickly symptoms of dementia would develop.
ST. PAUL, Minn.–Areas of the brain affected by Alzheimer's disease may start shrinking up to a decade before dementia is diagnosed, according to a new study published in the April 13, 2011, issue of Neurology®, the medical journal of the American Academy of Neurology.
BUFFALO, N.Y. -- A just released study on the relationship between multiple sclerosis (MS) and chronic cerebral venous insufficiency (CCSVI), a narrowing of the extracranial veins that restricts the normal outflow of blood from the brain, found that CCSVI may be a result of MS, not a cause.
The study, conducted by University at Buffalo researchers, appears in the current issue of Neurology, the journal of the American Academy of Neurology.
In a breakthrough that may aid treatment of learning impairments, strokes, tinnitus and chronic pain, UT Dallas researchers have found that brain nerve stimulation accelerates learning in laboratory tests.
High levels of a protein associated with chronic, low-grade inflammation in the brain correlate with aspects of memory decline in otherwise cognitively normal older adults, according to a study led by scientists at the University of California, San Francisco.
The study is being reported in a poster session at the American Academy of Neurology annual meeting on Wednesday, April 13, 2011.
Up equals good, happy, optimistic; down the opposite. Right is honest and trustworthy. Left, not so much. That's what language and culture tell us. "We use mental metaphors to structure our thinking about abstract things," says psychologist Daniel Casasanto, "One of those metaphors is space."
Drugs already in development to treat Alzheimer's disease may eventually be tapped for a different purpose altogether: re-growing the ends of injured nerves to relieve pain and paralysis. According to a new Johns Hopkins study, experimental compounds originally designed to combat a protein that builds up in Alzheimer's-addled brains appear to make crushed or cut nerve endings grow back significantly faster, a potential boon for those who suffer from neuropathies or traumatic injuries.
A team of scientists at Penn State University, the Salk Institute for Biological Studies, and other institutions have developed a method for recreating a schizophrenic patient's own brain cells, which then can be studied safely and effectively in a Petri dish. The method brings researchers a step closer to understanding the biological underpinnings of schizophrenia.
Rett syndrome, a neurodevelopmental disorder on the autism spectrum, is marked by relatively normal development in infancy followed by a loss of loss of cognitive, social and language skills starting at 12 to 18 months of age. It is increasingly seen as a disorder of synapses, the connections between neurons that together form brain circuits. What hasn't been clear is why children start out developing normally, only to become progressively abnormal. New research from Children's Hospital Boston, published in the April 14 issue of Neuron, helps unravel what's going on.
A new MRI device that guides surgeons as they implant electrodes into the brains of people with Parkinson's disease and other neurological disorders could change the way this surgery, called deep brain stimulation, is performed at medical centers across the country, according to a group of doctors at University of California, San Francisco.
JUPITER, FL, April 13, 2011 – Using advanced imaging technology, scientists from the Florida campus of The Scripps Research Institute have identified a change in chemical influx into a specific set of neurons in the common fruit fly that is fundamental to long-term memory.
The study was published in the April 13, 2011 issue of The Journal of Neuroscience.
Frog and toad skins already are renowned as cornucopias of hundreds of germ-fighting substances. Now a new report in ACS's Journal of Proteome Research reveals that the toad brains also may contain an abundance of antibacterial and antiviral substances that could inspire a new generation of medicines.
Tel Aviv — Human beings are well aware that hindsight is 20/20 — and the product of this awareness is often what we call "regret." Could this hindsight be programmed into a computer to more accurately predict the future? Tel Aviv University computer researchers think so — and the Internet giant Google is anxious to know the answer, too.
Pigeons may not instill the same aura of fear as a Tyrannosaurus rex, but they inherited their sense of smell from such prehistoric killers.
