Episodios

  • Laughing in the Face of Adversity

    15/11/2007 Duración: 01min

    A poster presented at the Society of Neuroscience meeting reveals that empathy isn't always about matching anothers' emotion. Researchers found that sometimes instead of feeling anothers' pain, we might feel more...amused.

  • The General Gist of False Memories

    08/11/2007 Duración: 01min

    Duke University neuroscientists have found a distinction between memories for specifics versus memories for the overall gist of an event. The latter, the overall impression we have of something, tends to be the memory that is more often false.

  • How We Can Hear Without Sound

    01/11/2007 Duración: 01min

    Research published in Nature describes how spontaneous activity in a developing ear creates the mechanics of hearing in the absence of sound. Researchers say this might help explain the tortuous ringing of tinnitus.

  • Sexual Orientation Controlled in the Brains of Worms

    25/10/2007 Duración: 01min

    Biologists are able to turn on a gene in the brain of nematode worms that leads them to desire same-sex partners.

  • Clock Genes Might Control the Sleep We Need

    18/10/2007 Duración: 01min

    Clock genes, long known to regulate our circadian rhythms, also give clues to what makes sleep so persistent.

  • God in the Brain?

    11/10/2007 Duración: 01min

    As neuroscientists search for brain circuits that lead to religious experiences, they're touching on some of our deepest questions - like, could religion be explained by a neural quirk? For more on this story, see David Biello's article, "Searching for God in the Brain" in this month's issue of Scientific American Mind.

  • New Head Protection for Footballers

    04/10/2007 Duración: 01min

    A new high-tech helmet allows coaches and sideline doctors to spot concussions and other dangerous injuries on the football field, in real-time. The head gear has sensors that send impact measurements wirelessly. For more on this story, please read Larry Greenemeier's October 4 article on Sciam.com news.

  • More Stress Means Less Eating

    27/09/2007 Duración: 01min

    Recent studies on a hormone receptor in the brain called CRF2 brought new hope for a solution to obesity. But research in the Journal of Neuroscience cautions: while CRF2 cuts appetite, it also increases stress.

  • Neurons for Good and Bad Surprises

    20/09/2007 Duración: 01min

    A recent study with monkeys finds that the amygdala, the emotional center of the brain, has neurons that fire for good surprises, and different neurons that fire for bad surprises.

  • Fetal Neurons Found in Adult Brain

    13/09/2007 Duración: 01min

    Special cells that control the wiring of a fetus' brain were thought to die off shortly after birth. But scientists have found some of these pre-natal neurons surviving, and communicating, in the adult brain.

  • Toddlers Beat the Great Apes at Social Learning

    06/09/2007 Duración: 01min

    New research in Science reveals that children and apes are on par when it comes to straight numerical and spatial abilities, but when they're tested on social learning, the children excel.

  • Going Under Hypnosis Before Going into Surgery

    30/08/2007 Duración: 01min

    Turns out that hypnosis, once thought to be a hocus-pocus parlor trick, may now be considered a legitimate surgical tool

  • Women Really do Prefer Pink

    23/08/2007 Duración: 01min

    A study has shown that women are more attracted to reddish hues, than to greens, yellows and the universally-loved blues.
