Memories Can Be Passed Down Through DNA - YouTube - 0 views

  •  
    The premise of Assassin's Creed is the reliving of other people's memories stored inside DNA. Well scientists have found that in mice, it actually happens! Anthony is joined by special guest and our friend Tara Long from Hard Science to explain how this process works, and if it might apply to humans as well.

Diets Heavy In Fructose Damage Genes Related To Memory And Metabolism, Says Study - Forbes - 0 views

  •  
    The study is the first to examine all of the gene networks affected by fructose that result in changes to brain function and metabolism-more than 20,000 genes in total. Although the study was conducted using rats, the researchers report that the majority of the sequenced genes are comparable to those in humans, including more than 200 genes in the hippocampus, a brain area crucial to memory, and 700 in the hypothalamus, the seat of the brain's metabolic control center.

Brain Workouts - National Center for Case Study Teaching in Science - 0 views

  •  
    This directed case study follows two college roommates, Darrell and Anthony, who have just returned to school after winter vacation. They share that their ageing fathers are concerned about their declining faculties and are amused by their fathers' efforts to reverse the process.  Darrell's dad plays "brain games" on the computer while Anthony's father believes running will slow his memory decline. Intrigued, the roommates search through their biopsychology class notes to find out whether their fathers are correct. They review the topics of synaptic formation and plasticity, including axonal and dendritic development, and chemical factors in the brain that promote the survival and growth of neurons or stop the genetically programmed death of neurons. Based on research findings, students reading this case will decide whether Darrell and Anthony's fathers are correct in their assertions. The case is appropriate for a wide variety of courses including introductory anatomy or physiology, or for upper-division biopsychology, biology, or neuroscience courses.

Why elephants never forget - Alex Gendler - YouTube - 0 views

  •  
    It's a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth. Alex Gendler takes us into the incredible, unforgettable mind of an elephant.

Your Dog Forgets You When You Leave - YouTube - 0 views

  •  
    When you leave the house, does your dog or cat even remember you? Read More: A Rat's Tenacious Memory http://www.indiana.edu/~rcapub/v17n1/... "In the wild, rats scramble over the network of pathways they have created, combing their surroundings for food, water, mates, and shelter. Their movements may seem automatic to the untrained eye, simply a reflexive pattern. Decades ago, however, researchers established that rats know where they are going and remember where they have been."

Study in mice shows Zika virus also attacks adult brain cells | Reuters - 0 views

  •  
    U.S. researchers have found that Zika can attack special populations of brain cells in adult mice in the part of the brain involved in learning and memory, raising new questions about how the virus may be impacting millions of adults who have been infected with the virus. The findings, published on Thursday in the journal "Cell Stem Cell," are the first to look at whether Zika can attack the same kinds of cells in adult mice that they do in fetal mice.

What Happens When You Go Under? How Anesthesia Works - YouTube - 0 views

  •  
    October 16 is World Anesthesia Day, celebrating the 170th anniversary of the first successful demonstration of surgical anesthesia. Prior to then, surgery was really unpleasant, to put it mildly -- surgeons turned to alcohol, narcotics and even smacking their patients on the head to induce unconsciousness. Fortunately, anesthesia now allows tens of thousands patients every day to avoid the pain and memories of their procedures. But how does anesthesia work? This week, Reactions looks at scientists' current understanding of what happens when you go under.

Medicine in the Genomic Era | HHMI's BioInteractive - 0 views

  •  
    In the 2013 Holiday Lectures on Science, Charles L. Sawyers of Memorial Sloan-Kettering Cancer Center and Christopher A. Walsh of Boston Children's Hospital will reveal the breathtaking pace of discoveries into the genetic causes of various types of cancers and diseases of the nervous system, and discuss the impact of those discoveries on our understanding of normal human development and disease.

DNA breakage underlies both learning, age-related damage | MIT News - 0 views

  •  
    Early-response genes, which are important for synaptic plasticity, are "switched off" under basal conditions by topological constraints. Neuronal activity triggers DNA breaks in a subset of early-response genes, which overrides these topological constraints, and "switches on" gene expression.

Alzheimer's study finds possible cause of disease | Society | The Guardian - 0 views

  •  
    The research suggests that in mice with Alzheimer's disease certain immune cells that normally protect the brain begin abnormally to consume an important nutrient called arginine. By blocking this process using the drug difluoromethylornithine (DFMO), memory loss and a buildup of sticky proteins known as brain plaques were prevented.

    Since the day you were born, a slimy, three-pound blob has controlled your every thought, memory, movement, and emotion. Visual perception, creativity, lying, and persuasion are just a few of the mental skills explored in the new television series Brain Games from the National Geographic Channel.

How A High-Fat Diet Could Damage Your Brain - Forbes - 0 views

  •  
    The conclusion is that the high-fat diet triggered chronic inflammation, which in turn triggered an autoimmune response in the mice's central nervous systems. Normally this response protects the brain from invaders like bacteria, but a high-saturated fat diet knocks the process off track, resulting in damage to synapses in the brain - specifically in the hippocampus. Since the hippocampus is a brain area central to memory and learning, the eventual outcome is impaired brain function. In short, the high-fat diet caused brain damage.

Scientists have found an exciting new clue about how 'super-agers' stay sharp as they age - 0 views

  •  
    Research has shown that some older people stay sharp into old age and retain the ability to recall personal experiences with just as much accuracy as their middle-aged peers. The brains of these so-called "super-agers" look distinct, too: Their gray-matter-rich outer layer, or cortex, is thicker.
