How much does environment influence intelligence? Several years ago University of Virginia Professor Eric Turkheimer demonstrated that growing up in an impoverished and chaotic household suppresses I.Q. – without nurture, innate advantages vanish. What about genes? They matter too. After decades of research most psychologists agree that somewhere between 50% and 80% of intelligence is genetic. After all, numerous studies demonstrate that identical twins raised apart have remarkably similar I.Q.’s.

Twentysomethings just want to have fun, or at least remember it that way YanLev/iStockphoto/Thinkstock. Twentysomethings are having a moment. They’re inspiring self-help guides (see Meg Jay’s The Defining Decade: Why Your Twenties Matter—And How To Make the Most of Them Now ), hit television shows , Tumblrs -turned- handbooks , and lyrical New Yorker think pieces . What is it about twentysomethings ? Robin Henig asked in the New York Times Magazine not too long ago.
—Paul Stokes, MD, PhD Almost weekly, research reveals the tremendous neuroplasticity of the human brain . However, most prior studies pointed to the adaptability of the larger, more superficial cerebral cortex . The deeper, primitive ( limbic ) brain was seen as an evolutionary holdover that simply responded to the impulses sent from the higher cortex.

Some 30,000 neuroscientists have converged on the New Orleans convention center, a stone's throw from the French Quarter and overlooking the Mississippi river as it flows into the Gulf. Just as the river always flows downstream, science flows forward toward new understanding and nowhere is it more evident than here. I'm at the annual Society for Neuroscience (SfN) conference, which starts today and ends Wednesday.

WASHINGTON (Reuters) - Biogen Idec Inc said on Friday it will charge $54,900 a year for its multiple sclerosis drug, Tecfidera, which received U.S. approval on Wednesday. The company has priced the drug at a discount to key competitors such as Novartis AG's MS pill Gilenya, which costs roughly $60,000 a year, in a bid to maximize its market share. "We think this represents solid value to the MS community and demonstrates our commitment to patient access," said Kate Niazi-Sai, a Biogen spokeswoman. ... <p style="text-align:right;color:#A8A8A8"></p>

Premise #1: “The mind is in the body.” I teach a lot of courses and workshops on mind-body science, and Premise #1 is how I start all of them. It's a basic assumption of modern psychology, especially for those who study the brain .
In an astonishing new study, scientists at the National Institutes of Health (NIH), have imaged human and monkey brains and found… well, the image above says it all. It turns out that the pathways in your brain — the connections between neurons — are almost perfectly grid-like. It’s rather weird: If you’ve ever seen a computer ribbon cable — a flat, 2D ribbon of wires stuck together, such as an IDE hard drive cable — the brain is basically just a huge collection of these ribbons, traveling parallel or perpendicular to each other. There are almost zero diagonals, nor single neurons that stray from the neuronal highways. The human brain is just one big grid of neurons — a lot like the streets of Manhattan, minus Broadway, and then projected into three dimensions. This new imagery comes from a souped-up MRI scanner that uses diffusion spectrum imaging to detect the movement of water molecules within axons (the long connections made by neurons).
