    The human hippocampus sits at the base of the brain. It stores memories, helps regulate emotions and guides navigation by spatial processing.It’s the first part of the brain impaired by Alzheimer’s; hippocampus degeneration also can cause epilepsy and other diseases.“Like a new atlas, we’ve constructed the most detailed diagram of the hippocampus to date. With a better map, we can see each region and how it functions,” said Dr. Michael Bienkowski, co-lead author of the study.“A better map is a resource scientists can use to better understand the hippocampus and how its degeneration leads to diseases.”“Researchers can use the new...

    ... The offspring of partying adolescents, specifically those who used THC, may be at increased risk for mental illness and addiction as a result of changes to the epigenome — even if those children are years away from being conceived. The epigenome is a record of molecular imprints of potent experiences, including cannabis exposure, that lead to persistent changes in gene expression and behavior, even across generations. Though the critical studies are only now beginning, many neuroscientists prophesize a social version of Rachel Carson’s “Silent Spring,” in which we learn we’ve burdened our heirs only generations hence.

    People who have it say it can be excruciating. Tinnitus causes pain and a constant ringing in the ears that makes it almost impossible to concentrate or enjoy a social gathering. Worst of all, there's little they can do about it. There are treatments that can help, but no cure. Now, neuroscientists at Georgetown University Medical Center and colleagues in Germany say they've discovered the brain condition that causes it. It's not a cure, but researchers say it is the first step toward finding one. Writing in Trends in Cognitive Sciences, the scientists describe how the brain mechanisms that normally...

    The biggest thing Donald Trump is doing is realigning public perceptions on immigration among the low-information voters, for whom being seen as moderate and reasonable is more important than issue analysis. Up until now, nobody has been able to force the ideas Trump has espoused into the mainstream media. As a result, the perception of what is moderate has drifted to the left, and we have been, up until now, unable to stop it. This part of this book has a good example of the cognitive principle that Trump's rhetoric is affecting in low information voters. P is less committed...

    The mouse walked, the mouse stopped; the mouse ignored a bowl of food, then scampered back and gobbled it up, and it was all controlled by neuroscientists, researchers reported on Thursday. The study, describing a way to manipulate a lab animal's brain circuitry accurately enough to turn behaviors both on and off, is the first to be published under President Barack Obama's 2013 BRAIN Initiative, which aims to advance neuroscience and develop therapies for brain disorders. The point of the remote-control mouse is not to create an army of robo-rodents. Instead, neuroscientists hope to perfect a technique for identifying brain...

    Dozens of neuroscientists are protesting Europe’s $1.6 billion attempt to recreate the functioning of the human brain on supercomputers, fearing it will waste vast amounts of money and harm neuroscience in general. The 10-year Human Brain Project is largely funded by the European Union. In an open letter issued Monday, more than 190 neuroscience researchers called on the EU to put less money into the effort to “build” a brain, and to invest instead in existing projects. …

    Glia, the non-neuronal cells that make up most of the brain, must not be left out of an ambitious US mapping initiative, says R. Douglas Fields. The Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative announced by US President Barack Obama in April seeks to map and monitor the function of neural connections in the entire brains of experimental animals, and eventually in the human cerebral cortex. Several researchers have raised doubts about the project, cautioning that mapping the brain is a much more complex endeavour than mapping the human genome, and its usefulness more uncertain. I believe that exploring...

    Using direct human brain recordings, a research team from Drexel University, the University of Pennsylvania, UCLA and Thomas Jefferson University has identified a new type of cell in the brain that helps people to keep track of their relative location while navigating an unfamiliar environment. The "grid cell," which derives its name from the triangular grid pattern in which the cell activates during navigation, is distinct among brain cells because its activation represents multiple spatial locations. This behavior is how grid cells allow the brain to keep track of navigational cues such as how far you are from a starting...

    Controlling the movements of a helicopter just with your mind sounds like something out of a science fiction movie, but scientists at the University of Minnesota have made it a reality. They have learned to use their thoughts to steer a model helicopter around a gym, making it dip, rise, turn, and even fly through a ring. The scientists have published their study in the Journal of Neural Engineering. The development of brain computer interfacing (BCI) is to provide the user with the ability to communicate with the world outside and manipulate objects through thought modulation. Achieving this is accomplished...

    You don’t have to be a brain surgeon to find the subject of how our brains work fascinating. As Sally Satel points out in an interview with National Review Online’s Kathryn Jean Lopez, because the “brain is a very attractive topic to both readers and journalists . . . the sheer numbers of articles present many opportunities for the dissemination of overwrought claims.” But when news about the brain becomes hype, it can become a disseminator of “false hope and false answers.” As we look at the mechanics of the brain, we shouldn’t “become too carried away with the notion...

    Epigenetic changes affect neurotransmitters that lead to pair-bond formation. Love really does change your brain — at least, if you’re a prairie vole. Researchers have shown for the first time that the act of mating induces permanent chemical modifications in the chromosomes, affecting the expression of genes that regulate sexual and monogamous behaviour. The study is published today in Nature Neuroscience1. Prairie voles (Microtus ochrogaster) have long been of interest to neuroscientists and endocrinologists who study the social behaviour of animals, in part because this species forms monogamous pair bonds — essentially mating for life. The voles' pair bonding, sharing...

    Karl Deisseroth is leaving his mark on brain science one technique at a time. When Karl Deisseroth moved into his first lab in 2004, he found himself replacing a high-profile tenant: Nobel-prizewinning physicist Steven Chu. “His name was still on the door when I moved in,” says Deisseroth, a neuroscientist, of the basement space at Stanford University in California. The legacy has had its benefits. When chemistry student Feng Zhang dropped by looking for Chu, Deisseroth convinced him to stick around. “I don't think he knew who I was. But he got interested enough.” Deisseroth is now a major name...

    Brains of high-IQ people automatically ignore the least relevant sights People with high IQs see the world in their own way. Their brains seamlessly separate the visual wheat from the chaff, allowing them to home in on the most relevant information, a new study finds. Using a simple visual exercise, a team led by psychologist Duje Tadin of the University of Rochester in New York found that high-IQ volunteers excelled at detecting the direction in which small objects moved but struggled at tracking large moving objects. That’s a useful trait, the scientists report May 23 in Current Biology. In many...

    New York - Scientists have for the first time linked the brains of a human and a rat, enabling the man to use just his thoughts to wiggle the rodent's tail. This is the first case of a brain-to-brain interface between species, and the first example of a noninvasive brain-to-brain interface, researchers claimed. Earlier this year, scientists had linked together the brains of two rats.This first known instance of a brain-to-brain interface apparently helped the rodents share data to accomplish certain tasks, even across intercontinental distances, LiveScience reported. In the latest experiment, researchers from Harvard Medical School employed noninvasive techniques...

    Drugs made from magic mushrooms could help treat people with severe depression, a new study suggests. Scientists believe that the chemical psilocybin, the psychedelic ingredient in magic mushrooms, can turn down parts of the brain that are overactive in severely depressive patients, the Guardian reported. The drug appears to stop patients dwelling on themselves and their own perceived inadequacies. However, a bid by British scientists to carry out trials of psilocybin on patients in order to assess its full medical potential has been blocked by red tape relating to Britain’s strict drugs laws.

    When not misfolded, prions lend a hand in forming neuronal connections. Prions are best known as the infectious agents that cause ‘mad cow’ disease and the human versions of it, such as variant Creutzfeldt–Jakob Disease. But the proteins also have at least one known useful function, in the cells that insulate nerves, and are suspected to have more. Now researchers have provided the first direct evidence that the proteins play an important role in neurons themselves. The team reports in the Journal of Neuroscience1 that prions are involved in developmental plasticity, the process by which the structure and function of...
