Boston—If you were working on something at your computer and a gorilla floated across your computer screen, would you notice it? You would like to think yes, however, research shows that people often miss such events when engaged in a difficult task. This is a phenomenon known as inattentional blindness (IB). In a new study from Brigham and Women's Hospital (BWH) in Boston, researchers have found that even expert searchers, operating in their domain of expertise, are vulnerable to inattentional blindness. This study published this week Psychological Science.

Maternal alcohol consumption during pregnancy has detrimental effects on fetal central nervous system development. Maternal alcohol consumption prior to and during pregnancy significantly affects cognitive functions in offspring, which may be related to changes in cyclin-dependent kinase 5 because it is associated with modulation of synaptic plasticity and impaired learning and memory. Prof.
Recent studies have found that anesthesia drugs have neurotoxicity on the developing neurons, causing learning and memory disorders and behavioral abnormalities. Ketamine is commonly used in pediatric anesthesia. A clinical retrospective study found that children below 3 years old who receive a long time surgery, or because of surgery require ketamine repeatedly will exhibit the performance of school-age learning and memory disorders and behavioral abnormalities. Research group speculates that these abnormalities may be related to the potential neurotoxicity of ketamine.
Uruguay has it. So does Latvia, and Senegal. In fact, more than half of the world's countries have some degree of a guaranteed, specific right to public health and medical care for their citizens written into their national constitutions.
Controversy exists over what some mental health experts call "hypersexuality," or sexual "addiction." Namely, is it a mental disorder at all, or something else? It failed to make the cut in the recently updated Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, considered the bible for diagnosing mental disorders. Yet sex addiction has been blamed for ruining relationships, lives and careers.
A new study reports that subdiaphragmatic vagotomy reduces intake of sweet-tasting solutions in rats, and eliminate the hedonic perception produced by sucrose and saccharin in rats. Previous studies have shown that taste information and digestion information in animals during diet intake interact with each other in the central nervous system. So, how does subdiaphragmatic vagotomy influence the intake of sweet-tasting solution in rats? According to a study published in the Neural Regeneration Research (Vol. 8, No.

To write this little piece of text, the brain sends commands to arms and fingers to tap on the keyboard. Neuronal cells with their cable-like extensions, such as axons, transfer this information as electrical pulses that trigger muscles to move. The axonal signal speed can be to up to 100m/s in myelinated axons along the spinal cord.
Babies have an innate biological need to be attached to caregivers, usually their parents. But what happens when babies spend a night or more per week away from a primary caregiver, as increasingly happens in cases where the parents share custody, but do not live together?
In a new national study, University of Virginia researchers found that infants who spent at least one night per week away from their mothers had more insecure attachments to the mother compared to babies who had fewer overnights or saw their fathers only during the day.
Chronic obstructive pulmonary disease (COPD) is associated with an increased risk of developing cerebral microbleeds, according to a new study from researchers in the Netherlands. Cerebral microbleeds are a marker of cerebral small vessel disease, an important cause of age-related disability and cognitive decline.
Here's yet another reason to get off the couch: new research findings suggest that regularly breaking a sweat may lower the risk of having a stroke.
A stroke can occur when a blood vessel in the brain gets blocked. As a result, nearby brain cells will die after not getting enough oxygen and other nutrients. A number of risk factors for stroke have been identified, including smoking, high blood pressure, diabetes and being inactive.
Children born with a complete absence of the external ear canal, even if only one ear is affected, are more likely than their peers to struggle in school, according to new research at Washington University School of Medicine in St. Louis.
PROVIDENCE, R.I. – Rhode Island Hospital researchers have found that multiple factors contribute to the burden felt by caregivers of people living with Alzheimer's and other forms of dementia. These factors include the direct impact of providing care upon the caregivers' lives, guilt, and frustration or embarrassment. The study is published online in advance of print in American Journal of Geriatric Psychiatry.
University of Arizona researchers have found in a recent study that ultrasound waves applied to specific areas of the brain appear able to alter patients' moods. The discovery has led the scientists to conduct further investigations with the hope that this technique could one day be used to treat conditions such as depression and anxiety.
Social media has expanded to reach an unlikely new target: molecules. Scientists at the National Institute of Standards and Technology (NIST) have created networks of molecular data similar to Facebook's recently debuted graph search feature. While graph search would allow Facebook users to find all their New York-living, beer-drinking buddies in one quick search, the NIST-designed networks could help scientists rapidly sift through enormous chemical and biological data sets to find substances with specific properties, for example all 5-ring chemicals with an affinity for enzyme A.
Alexandria, Va., USA – Today, the International and American Associations for Dental Research (IADR/AADR) published a paper titled "Gingivae Contain Neural-crest- and Mesoderm-derived Mesenchymal Stem Cells." The paper, written by lead author Songtao Shi, Center for Craniofacial Molecular Biology, Ostrow School of Dentistry, University of Southern California, Los Angeles, USA, is published in the OnlineFirst portion of the IADR/AADR Journal of Dental Research.
