    Even brain images can be biased

    An astonishing number of things that scientists know about brains and behavior are based on small groups of highly educated, mostly white people between the ages of 18 and 21. In other words, those conclusions are based on college students.

    College students make a convenient study population when you’re a researcher at a university. It makes for a biased sample, but one that’s still...

    In a tally of nerve cells in the outer wrinkles of the brain, a dog wins

    If more nerve cells mean more smarts, then dogs beat cats, paws down, a new study on carnivores shows. That harsh reality may shock some friends of felines, but scientists say the real surprises are inside the brains of less popular carnivores. Raccoon brains are packed with nerve cells, for instance, while brown bear brains are sorely lacking.

    By comparing the numbers of nerve cells, or...

    Brains of former football players showed how common traumatic brain injuries might be

    There have been hints for years that playing football might come at a cost. But a study this year dealt one of the hardest hits yet to the sport, detailing the extensive damage in football players’ brains, and not just those who played professionally.       

    In a large collection of former NFL players’ postmortem brains, nearly every sample showed signs of chronic traumatic...

    Zika cases are down, but researchers prepare for the virus’s return

    One of the top stories of 2016 quietly exited much of the public’s consciousness in 2017. But it’s still a hot topic among scientists and for good reasons. After Zika emerged in the Western Hemisphere, it shook the Americas, as reports of infections and devastating birth defects swept through Brazil and Colombia, eventually reaching the United States. In a welcome turn, the number of Zika...

    Mini brains may wrinkle and fold just like ours

    PHILADELPHIA — Flat brains growing on microscope slides may have revealed a new wrinkle in the story of how the brain folds.

    Cells inside the brains contract, while cells on the outside grow and push outward, researchers at the Weizmann Institute of Science in Rehovot, Israel, discovered from working with the lab-grown brains, or organoids. This push and pull results in folds in the...

    Scientists are seeking new strategies to fight multiple sclerosis

    James Davis used to be an avid outdoorsman. He surfed, hiked, skateboarded and rock climbed. Today, the 48-year-old from Albuquerque barely gets out of bed. He has the most severe form of multiple sclerosis, known as primary progressive MS, a worsening disease that destroys the central nervous system. Diagnosed in May 2011, Davis relied on a wheelchair within six months. He can no longer get...

  • 50 years ago, artificial limbs weren’t nearly as responsive

    Electric limbs

    Very subtle control of artificial limbs by means of a tiny electronic device may become possible.… [The] electronic device … [is] designed to be injected into a muscle through a thick hypodermic needle. A tiny package strapped to the outside of the limb will beam radio waves at the device, which will return them, modified by the electric current produced in the muscle. — ...

    Study casts doubt on whether adult brain’s memory-forming region makes new cells

    In stark contrast to earlier findings, adults do not produce new nerve cells in a brain area important to memory and navigation, scientists conclude after scrutinizing 54 human brains spanning the age spectrum.

    The finding is preliminary. But if confirmed, it would overturn the widely accepted and potentially powerful idea that in people, the memory-related hippocampus constantly churns...

    The brain’s helper cells have a hand in learning fear

    WASHINGTON, D.C. — Helper cells in the brain just got tagged with a new job — forming traumatic memories.

    When rats experience trauma, cells in the hippocampus — an area important for learning — produce signals for inflammation, helping to create a potent memory. But most of those signals aren’t coming from the nerve cells, researchers reported November 15 at the Society for Neuroscience...

    See these first-of-a-kind views of living human nerve cells

    The human brain is teeming with diversity. By plucking out delicate, live tissue during neurosurgery and then studying the resident cells, researchers have revealed a partial cast of neural characters that give rise to our thoughts, dreams and memories. 

    So far, researchers with the Allen Institute for Brain Science in Seattle have described the intricate shapes and electrical properties...
