Binge eaters' dopamine levels spike at sight, smell of food Monday, February 28, 2011 Brain scans comparing the effects of methylphenidate plus food stimulation to placebo plus neutral stimulation in obese binge eaters and obese control subjects who were not binge eaters. Since the radiotracer competes with the brain’s natural dopamine to bind to receptors, a weaker signal from the tracer (less red) indicates more dopamine in the brain. The decrease in red in the binge eaters exposed to food and methylphenidate (lower right) compared to the placebo/neutral stimulation condition (lower left) therefore indicates that food stimulation triggered a spike in dopamine levels in these subjects. A brain imaging study at the U.S. "These results identify dopamine neurotransmission, which primes the brain to seek reward, as being of relevance to the neurobiology of binge eating disorder," said study lead author Gene-Jack Wang, a physician at Brookhaven Lab and the Mount Sinai School of Medicine.

A rich club in the human brain Wednesday, November 2, 2011 This image shows the group connectome, with the nodes and connections colored according to their rich-club participation. Green represents few connections. Red represents the most. Credit: Reprinted with permission: Van den Heuvel, et al. The Journal of Neuroscience 2011 Just as the Occupy Wall Street movement has brought more attention to financial disparities between the haves and have-nots in American society, researchers from Indiana University and the University Medical Center Utrecht in The Netherlands are highlighting the disproportionate influence of so called "Rich Clubs" within the human brain. Not all regions of the brain, they say, are created equal. "We've known for a while that the brain has some regions that are 'rich' in the sense of being highly connected to many other parts of the brain," said Olaf Sporns, professor in the Department of Psychological and Brain Sciences in IU's College of Arts and Sciences.
Explaining emotion in the brain Emotion has become a well-represented, and well-respected, topic of neuroscientific inquiry, as borne out by its exponential increase in citation indices (e.g. increases in publications with the word in their title by 300 in the 1980s, by 900 in the 1990s and by >1600 in the past 6 years according to Science Citation Index). The reasons for this increase lie with advances both in our theoretical understanding of emotions and in the development of new tools for exploring their neural basis—notably functional neuroimaging. These efforts have resulted in important advances also in the diagnosis and treatment of neurological and psychiatric diseases, many of which feature dysfunctional emotions as one of the most disabling components. It is thus timely to take stock of what we have learned, and to publish books that summarize the state of the field. Edmund Rolls' latest book, Emotion Explained, provides such a summary.

New neurons help us to remember fear Fear burns memories into our brain, and new research by University of California, Berkeley, neuroscientists explains how. Scientists have long known that fear and other highly emotional experiences lead to incredibly strong memories. In a study appearing online today (Tuesday, June 14) in advance of publication in the journal Molecular Psychiatry, UC Berkeley’s Daniela Kaufer and colleagues report a new way for emotions to affect memory: The brain’s emotional center, the amygdala, induces the hippocampus, a relay hub for memory, to generate new neurons. The figure shows newly born nerve cells (green) colocalizing with a neuronal marker which indicates immature nerve cells (red). In a fearful situation, these newborn neurons get activated by the amygdala and may provide a “blank slate” on which the new fearful memory can be strongly imprinted, she said. “Many affective disorders involve disordered emotional memories like PTSD, depression and anxiety.

Children are naturally prone to be empathic and moral Related images(click to enlarge) University of Chicago Children between the ages of seven and 12 appear to be naturally inclined to feel empathy for others in pain, according to researchers at the University of Chicago, who used functional Magnetic Resonance Imaging (fMRI) scans to study responses in children. The responses on the scans were similar to those found in studies of adults. Researchers found that children, like adults, show responses to pain in the same areas of their brains. "This study is the first to examine in young children both the neural response to pain in others and the impact of someone causing pain to someone else," said Jean Decety, Professor in the Departments of Psychology and Psychiatry at the University of Chicago, who reported the findings in the article, "Who Caused the Pain? The programming for empathy is something that is "hard-wired" into the brains of normal children, and not entirely the product of parental guidance or other nurturing, said Decety.
7 Man-Made Substances that Laugh in the Face of Physics The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive. But mankind isn't happy to accept the weirdness of nature when we can create our own abominations of science that, due to the miracle of technology, spit in nature's face and call it retarded. That's why we came up with... #7. Ferrofluids What do you get when you suspend nanoparticles of iron compounds in a colloidal solution of water, oil and a surfactant? A ferrofluid is a liquid that reacts to magnetic fields in trippy ways that make you think that science is both magical and potentially evil. Tell us that didn't look like the birth of the most sinister dildo ever. What happens is that when a magnetic field is applied to the fluid, the particles of iron compound inside align to it.

Researchers show that memories reside in specific brain cells Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams. But are engrams conceptual, or are they a physical network of neurons in the brain? In a new MIT study, researchers used optogenetics to show that memories really do reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory — explaining, for example, how Marcel Proust could recapitulate his childhood from the aroma of a once-beloved madeleine cookie. In that famous surgery, Penfield treated epilepsy patients by scooping out parts of the brain where seizures originated. Fast forward to the introduction, seven years ago, of optogenetics, which can stimulate neurons that are genetically modified to express light-activated proteins. False memory
Fossils Of 500 Million Year Old Marine Predator Anomalocaris Discovered | FinestDaily ShareShare A recent discovery in the field of paleontology reveals probably the oldest predator known to man. The fossils found on Kangaroo Island are being studied by scientists from the University of Adelaide, Australia. The fossilized eyes belonged to the 500 million-year-old Anomalocaris, a marine creature believed to be at the top of the food chain in prehistoric times. A full story regarding this subject will be available in December’s issue of Nature. Taking into consideration the studies so far, it seems that the Anomalocaris had extremely acute vision, considered better than any other insects or crustaceans, even by today’s standards. Thanks to the discovery of its eyes, meticulous analysis shows amazing details when it comes to optical design, with some similarities much alike contemporary crabs, flies and kin. These fossils make the Anomalocaris the ancestor of today’s arthropods, alongside other evolutionary implications that affect a lot of species.
5 Logical Fallacies That Make You Wrong More Than You Think The Internet has introduced a golden age of ill-informed arguments. You can't post a video of an adorable kitten without a raging debate about pet issues spawning in the comment section. These days, everyone is a pundit. But with all those different perspectives on important issues flying around, you'd think we'd be getting smarter and more informed. #5. Think about the last time you ran into a coworker or family member spouting some easily disproven conspiracy theory -- somebody who still thinks Obama's birth certificate is a fake or that Dick Cheney arranged 9/11 to cover up his theft of $2.3 trillion from the government. That has literally never happened in the history of human conversation. Getty"OK, so Dick Cheney doesn't have a third arm. The Science: It's called the argumentative theory of reasoning, and it says that humans didn't learn to ask questions and offer answers in order to find universal truths. Yes, kids, being a dick works. So During Your Next Argument, Remember ... #4.
100 Very Cool Facts About The Human Body The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Hair and Nails While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. Facial hair grows faster than any other hair on the body. Internal Organs Though we may not give them much thought unless they’re bothering us, our internal organs are what allow us to go on eating, breathing and walking around. The largest internal organ is the small intestine. Bodily Functions We may not always like to talk about them, but everyone has to deal with bodily functions on a daily basis. Sneezes regularly exceed 100 mph. Sex and Reproduction As taboo as it may be in some places, sex is an important part of human life as a facet of relationships and the means to reproduce. Senses
