Galanin neurons in the brain's medial preoptic area that appear to regulate parental behavior, a mouse study finds. If similar neurons are at work in humans, it could offer clues to the treatment of conditions like post-partum depression. "If you look across different animal species, there are some species in which the father contributes to caring for the young -- sometimes the work is divided equally,...

Tinnitus affects roughly 50 million people and is now the number one disability among our men and women in uniform, costing the U.S. about $1.7 billion a year to treat. But even with these staggering numbers, there's still no know cure for tinnitus. Finding a solution to lessen symptoms can be just as challenging, but physicians now have a growing range of options to offer patients to help manage symptoms...

The gene that controls blood-brain barrier permeability through a little-studied phenomenon calledtranscytosis has been identified by researchers for the first time. The study, which was conducted in mice, offers a new way to devise strategies to open the blood-brain barrier for drug delivery or restore it in neurological disease. ...

The venom from marine cone snails, used to immobilize prey, contains numerous peptides called conotoxins, some of which can act as painkillers in mammals. Researchers provide new insight into the mechanisms by which one conotoxin, Vc1.1, inhibits pain. ...

A commonly prescribed antidepressant can reduce production of the main ingredient in Alzheimer’s brain plaques, according to new research. The findings, in mice and people, support preliminary studies that evaluated a variety of antidepressants. Brain plaques are tied closely to memory problems and other cognitive impairments caused by Alzheimer's disease. Stopping plaque buildup may halt the disastrous...

Reduction in brain volume in the hippocampus (a region related to memory) was seen in patients with the psychotic disorders schizophrenia, schizoaffective disorder and psychotic bipolar disorder. The pathophysiology of psychotic disorders remains unclear, especially schizoaffective disorder. Changes in volume in the hippocampus are a hallmark of schizoaffective disorder. Advances in image processing...

Individuals prenatally exposed to tobacco smoke exhibited weaker response in some regions of the brain while processing a task that measures inhibition control (the ability to control inappropriate responses). Prenatal tobacco smoke exposure is a risk factor for adverse physical and mental outcomes in children. Growing evidence suggests that smoking during pregnancy may increase the risk of psychopathology...

Our human brains are filled with maps: visual maps of our external environments, and motor maps that define how we interact physically within those environments. Somehow these separate points of reference need to correspond with -- and to -- one another in order for us to act, whether it's grasping a coffee cup or hitting a tennis ball. ...

Possible new ways to image glioblastoma multiforme tumors -- a form of brain tumor -- using the SapC-DOPS technology have been revealed by researchers. Brain tumors are an extremely serious example of this and are not only difficult to treat -- both adult and pediatric patients have a five-year survival rate of only 30 percent -- but also have even been difficult to image, which could provide important...

Between 2006 and 2010, there was a nearly 30 percent increase in the rate of visits to an emergency department for traumatic brain injury, which may be attributable to a number of factors, including increased awareness and diagnoses, according to a study. In the last decade, traumatic brain injury (TBI) garnered increased attention, including public campaigns and legislation to increase awareness and...

The transporter protein Mfsd2a carries DHA to the brain, research has found. The findings have widespread implications for how DHA functions in human nutrition. The study marks the first time a genetic model for brain DHA deficiency and its functions in the brain has been made available. DHA is an omega-3 fatty acid most abundantly found in the brain that is thought to be crucial to its function. However,...

Using new stem cell technology, scientists have shown that neurons generated from the skin cells of people with schizophrenia behave strangely in early developmental stages, providing a hint as to ways to detect and potentially treat the disease early. "This study aims to investigate the earliest detectable changes in the brain that lead to schizophrenia," says one researcher. "We were surprised at...

Alzheimer's research has centered on trying to understand the protective or regenerative properties of brain cells as an avenue for treating the widespread disease. Now a researcher has discovered novel protein fragments that have proven protective properties for cognitive functioning. Her findings have the potential to serve as a pipeline for new drug candidates to treat the disease. ...

Mutations in two presenilin proteins associated with familial Alzheimer's disease disrupt the flow of calcium ions within neurons. Researchers have found that suppressing the hyperactivity of the calcium channels alleviated FAD-like symptoms in mice models of the disease. These new observations suggest that approaches based on modulating calcium signaling could be explored for new AD therapies. ...

Some primate species will wait more than two minutes if they know they will get a larger serving of food -- while others are unable to wait more than a few seconds. A new study probes the evolutionary reasons for the difference. ...

Students who take 'smart drugs' risk long-term damage to the brain's working memory and ability to move efficiently from one task to another. Over a million American students misuse prescription drugs or take illegal stimulants to increase their attention span, memory, and capacity to stay awake. Such "smart drugs" become more and more popular due to peer pressure, stricter academic requirements, and...

In Western tradition, meditation is linked to a personal relationship with God. Asiatic meditation places more emphasis on techniques, according to new research. Meditation is practiced in Norway as well as in India. With or without a religious purpose. And with a wealth of different techniques. Meditation has been performed for several thousand years, and appears in all the major religions. But what...

Much like using dimmer switches to brighten or darken rooms, biochemists have identified a protein that can be used to slow down or speed up the growth of brain tumors in mice. Brain and other nervous system cancers are expected to claim 14,320 lives in the United States this year. ...
