Ep 3. How Smart Can We Get?

How Smart Can We Get? is a compelling and thought-provoking episode from season 6 of the popular science show NOVA scienceNOW. In this episode, host David Pogue explores the fascinating field of cognitive neuroscience and investigates the potential of the human brain.

Pogue begins by asking the fundamental question: How smart can we get? He delves into the various ways in which scientists have attempted to measure intelligence, from IQ tests to brain scans, and explains the limitations of these methods. He then introduces viewers to some of the most cutting-edge research in cognitive neuroscience, including studies on brain plasticity, memory, and learning.

Throughout the episode, Pogue interviews some of the leading researchers in the field, including Dr. Michael Merzenich, who has spent decades studying the brain's ability to change and adapt, and Dr. Adam Gazzaley, who is developing video games that can improve cognitive function. These experts provide valuable insights into the potential of the human brain and the ways in which we can improve our cognitive abilities.

One of the most fascinating parts of the episode is Pogue's exploration of brain training programs. He tries out several different programs himself, ranging from computer games to meditation, and discusses the effectiveness of each. He also speaks with researchers who have conducted studies on the efficacy of these programs and the impact they can have on cognitive abilities. Pogue ultimately concludes that while some programs may be more effective than others, it is clear that the brain can be trained and improved with the right kind of practice.

Another highlight of the episode is Pogue's interviews with people who have experienced dramatic changes in their cognitive abilities. He speaks with a woman who regained her ability to read after suffering a stroke, thanks to intensive brain training, and a man who was able to overcome his dyslexia using specialized computer programs. These testimonials serve as powerful examples of the potential of the human brain and the ways in which we can improve our cognitive abilities.

Overall, How Smart Can We Get? is an engaging and informative episode that offers a fascinating glimpse into the field of cognitive neuroscience. Pogue's easy-to-follow explanations and engaging interviews make complex scientific concepts accessible and relatable to viewers of all backgrounds. Whether you are a science enthusiast or simply curious about the potential of the human brain, this episode is definitely worth watching.
