A new study suggests that the inner sense of our cardiovascular state, our "interoceptive awareness" of the heart pounding, relies on two independent pathways, contrary to what had been asserted by prominent researchers. The University of Iowa study was published online this week in the journal Nature Neuroscience by researchers in the department of neurology in the Roy J. and Lucille A. Carver College of Medicine and the graduate programs in neuroscience and psychology. The researchers found...

People with psoriasis "“ an often distressing dermatological condition that causes lesions and red scaly patches on the skin "“ are less likely to react to looks of disgust by others than people without the condition, new research has found.University of Manchester scientists used magnetic resonance imaging (MRI) scans to compare the brains of 26 men, half of whom had chronic psoriasis. The researchers looked at the insular cortex "“ a part of the brain triggered by both...

UCLA psychologists have determined for the first time that a gene linked with physical pain sensitivity is associated with social pain sensitivity as well.Their study indicates that variation in the mu-opioid receptor gene (OPRM1), often associated with physical pain, is related to how much social pain a person feels in response to social rejection. People with a rare form of the gene are more sensitive to rejection and experience more brain evidence of distress in response to rejection than...

What is going on in teenagers' brains as their drive for peer approval begins to eclipse their family affiliations? Brain scans of teens sizing each other up reveal an emotion circuit activating more in girls as they grow older, but not in boys. The study by Daniel Pine, M.D., of the National Institute of Mental Health (NIMH), part of National Institutes of Health, and colleagues, shows how emotion circuitry diverges in the male and female brain during a developmental stage in which girls are...

Clinicians from the Centre hospitalier de l'Universit© de Montr©al (CHUM) have perfected an operation, which was previously considered too dangerous, to control refractory insular epilepsy, using an innovative microsurgery technique. According to a study published as the feature article in the latest issue of the Journal of Neurosurgery , the new surgical technique is both safe and beneficial for patients."Recent observations by our team and others confirm the previously unsuspected...

The brains of thrill seekers differ from those of who avoid risky behavior, U.S. researchers suggest. Psychologists Jane E. Joseph, Xun Liu, Yang Jiang and Thomas H. Kelly of the University of Kentucky, along with Donald Lyman of Purdue University, recruited two sets of volunteers -- high sensation seekers or low sensation seekers -- based on their responses to personality surveys and risk-taking questionnaires. Both groups were shown a variety of photographs -- ranging from mundane scenes of...

Why do people gamble if they know that the house always wins? Researchers at the University of Cambridge argue that near-misses, where the gambler narrowly misses out on the jackpot, may provide part of the answer.Although the gambler loses their bet on a near-miss, where the slot machine reel stops one position from the 'payline', the researchers found that near-miss outcomes make people want to carry on gambling and caused brain activity in areas that normally process winning money.The...

Duke University Medical System researchers have discovered there are differing taste pathways for nicotine, which could provide a new approach for future smoking-cessation products. "We learned some of nicotine's secrets," said Albino Oliveira-Maia, M.D., Ph.D., a postdoctoral fellow of the Duke Department of Neurobiology. "This is the first study to explore both the peripheral taste pathways activated by nicotine, and how these pathways are integrated in sensory areas of the brain." The...

Scientists at University College London (UCL) may have finally found an answer to explain the fine line between love and hate. UCL researchers Semir Zeki and John Paul Romaya discovered that brain scans of volunteers who were shown images of people they hated revealed activity that occurs in the same areas set off by romantic love. "This linkage may account for why love and hate are so closely linked to each other in life," wrote UCL researchers Semir Zeki and John Paul Romaya in a report...

PASADENA, Calif. -- In the biblical story in which two women bring a baby to King Solomon, both claiming to be the mother, he suggests dividing the child so that each woman can have half. Solomon's proposed solution, meant to reveal the real mother, also illustrates an issue central to economics and moral philosophy: how to distribute goods fairly. Now, researchers at the California Institute of Technology have discovered that reason struggles with emotion to find equitable solutions, and...
