Smart Pills: Drugs to Boost Brain Power

IQ-elevating agents that can boost brain power are being used by over 10% of university students. But how do these cognitive-equivalents of anabolic steroids for the brain actually work, what are their effects and are they safe? Moreover, is the advantage they confer an ethical one? And if not, should universities be screening students ahead of exams to deter their use? Meanwhile, in the news this week, we find out how lasers can cut complications in cataract surgery, why some people are allergic to wine, we hook up with the highlights from the world's biggest neuroscience meeting including the discovery of how the eye talks to the brain, and we hear how scientists have solved a long-standing mystery relating the structure of the placenta...

    A lot of us like a nice glass of wine at the end of the day, but for around 500 million people in the world, thatís not so much fun, as they have an allergy to wine. Itís apparently a bit like having a hayfever attack, with itchy eyes and sneezing. Now a group from the Universit...

  • 07:57 - Highlights from the Society for Neuroscience Meeting 2010

    This week, the the annual meeting of the Society for Neuroscience took place in San Diego, California. This is the largest meeting of neuroscientists from around the world who meet to discuss their latest research and the progress they're making in understanding how the brain w...

    Meera and Dave explore the structures that can shape-shift from one shape to another - also known as bistable structures...

  • 32:52 - Cognition Enhancing Drugs

    We find out what impact cognition enhancers, or "smart drugs" have on the brain, and ask why so many students have started taking them illicitly...

  • 43:00 - Ethical Aspects of Enhancement

    Brain-boosting drugs raise some interesting ethical questions, ones that weíre likely to need to address more and more as our understanding of the human body increases. We talk ethics with Professor Julian Savulescu, Director of the Oxford Uehiro Centre for Practical Ethics...

  • 50:09 - What happens when you stop taking cognition enhancing drugs?

    If these drugs are taken to help with exams, what happens when the exams are over? Does the body/brain go back to normal? Does this new found ability stay with the drug abuser? Or, worse yet, do things get worse, because the body is looking a crutch?
