Many healthcare professionals are failing to advise people with medical conditions that could affect their ability to drive whether they should get behind the wheel, according to research from the University of Warwick.
Researchers from the University's Warwick Medical School have found many healthcare professionals are failing to tell patients with certain conditions such as diabetes or visual impairment if they are not fit to drive.
How do the visual images we experience, which have no tangible existence, arise out of physical processes in the brain? New research at the Weizmann Institute of Science provided evidence, for the first time, that an 'ignition' of intense neural activity underlies the experience of seeing.
People with Parkinson's Disease are more likely to display abnormal social behaviour and make poor decisions in ambiguous circumstances if they are pathological gamblers, according to research in the January issue of the European Journal of Neurology.
A number of studies have already associated pathological gambling with Parkinson's, suggesting that it is a frequent impulse control disorder associated mainly with dopamine replacement therapy.
A simple and inexpensive eye test could aid detection and diagnosis of major neurological diseases such as Alzheimer's at an earlier stage than is currently possible, according to new research by UCL scientists.
A new study concludes that people tend to match their risk perceptions about policy issues with their cultural values, which may explain the intense disagreement about proposals to vaccinate elementary-school girls against human-papillomavirus (HPV). The study also says people's values shape their perceptions of expert opinion on the vaccine.
Athens, Ga. – Before patting yourself on the back for resisting that cookie or kicking yourself for giving in to temptation, look around. A new University of Georgia study has revealed that self-control—or the lack thereof—is contagious.
New research unravels the brain mechanisms that underlie the ability of a standard drug treatment for Parkinson's to elicit compulsive behaviors in some patients with the disease. The study, published by Cell Press in the January 14th issue of the journal Neuron, provides fascinating new insight into the brain mechanisms that underlie a predisposition to behavioral addictions, such as pathological gambling and shopping.
A new study provides insight into the molecular characteristics that make a brain susceptible to anxiety and depression and less likely to respond to treatment with antidepressant medication. The research, published by Cell Press in the January 14th issue of the journal Neuron, may lead to more effective strategies for treating depression, a major health concern throughout the world.
Our energy-hungry brains operate reliably and efficiently while processing a flood of sensory information, thanks to a sort of neuronal thermostat that regulates activity in the visual cortex, Yale researchers have found.
The actions of inhibitory neurons allow the brain to save energy by suppressing non-essential visual stimuli and processing only key information, according to research published in the January 13 issue of the journal Neuron.
CAMBRIDGE, Mass.—MIT neuroscientists have discovered that when it comes to new neurons in the adult brain, the squeakiest wheels get the grease.
"Before, scientists believed the cells with the most accurate performance were selected and the others were rejected," said Picower Institute for Learning and Memory researcher Carlos Lois. "Our study shows that it doesn't matter what the cells are doing, as long as they are doing something, even if it is wrong. It's like musicians being chosen in an audition based not on how well they play, but how loudly."
DURHAM, N.C. – Scientists at Duke University Medical Center have identified neurons in the songbird brain that convey the auditory feedback needed to learn a song.
Their research lays the foundation for improving human speech, for example, in people whose auditory nerves are damaged and who must learn to speak without the benefit of hearing their own voices.
We all have at one time or another experienced the typical signs of an infection: the fever, the listlessness, the lack of appetite. They are orchestrated by the brain in response to circulating cytokines, the signaling molecules of the immune system. But just how cytokines' reach extends beyond the almost impenetrable blood-brain barrier has been the topic of much dispute.
NEW YORK (January 13, 2010) – An excess of one type of serotonin receptor in the center of the brain may explain why antidepressants fail to relieve symptoms of depression for 50 percent of patients, a new study from researchers at Columbia University Medical Center shows.
A consortium of European researchers, coordinated by the Computer Vision Centre (CVC) of Universitat Autònoma de Barcelona (UAB), has developed HERMES, a cognitive computational system consisting of video cameras and software able to recognise and predict human behaviour, as well as describe it in natural language. The applications of the Hermes project are numerous and can be used in the fields of intelligent surveillance, protection of accidents, marketing, psychology, etc.
Boston, MA—Researchers from Boston University School of Medicine (BUSM) have found that angiotensin receptor blockers (ARBs)—a particular class of anti-hypertensive medicines—are associated with a striking decrease in the occurrence and progression of dementia. These findings appear in the January issue of the British Medical Journal.
