S1 O1 - The Aging Mind: What Changes?
23 czerwca 201636 minAging affects us all, and it's important to know how our cognitive functions change over our lives. Open with an examination of how fluid processing skills - such as episodic and working memory - tend to decline over time, whereas crystallized intelligence (how-to skills and accumulated knowledge) remains stable or even improves.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O2 - Why Don’t We Live Forever?
31 października 201633 minTake a look at how our genes influence the aging process. Professor Polk explores several theories for why we age and eventually die, then delves into the genetic mechanisms involved in aging. Find out how replication damages cells and why there is a limit to the number of healthy replications our cells can make.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O3 - Is Aging a Disease?
31 października 201629 minScientists debate whether aging is actually a disease, but the effects of aging indisputably resemble the symptoms of a disease. Here, examine three major mechanisms behind these effects: energy consumption, free radicals, and damage to our DNA. Then consider whether there could be a way to "cure" these effects.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O4 - Aging and Brain Structure
31 października 201628 minSee how the cognitive changes of aging relate to the biological changes discussed previously. It turns out that regions of the brain associated with processing speed, executive function, and episodic memory are more susceptible to aging, which may explain why these cognitive functions are particularly susceptible to decline.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O5 - Aging and Brain Function
31 października 201631 minTurn from the brain's structure to its activity. After reviewing how we study brain function via fMRI, Professor Polk demonstrates how brain activity changes as we age - and how these changes impact our memory, our ability to multitask, and more. Then, learn some good news about how the brain compensates for these changes.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O6 - Emotional Aging
31 października 201630 minSee what science knows about our evolving emotional landscape, and why older people tend to be happier than the young. Depression can still be a problem for older adults, though - consider the most common causes, discover how symptoms may differ from those of younger people, and learn to match the treatment to the situation.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O7 - Strategies for an Aging Memory
31 października 201631 minHow does memory work? Can aspects of it be improved? Here, get a test of two different strategies for memorization: sheer repetition on the one hand, and visual-spatial storytelling on the other. Once you understand how memory works, you'll investigate four key principles that you can apply to improve your own memory.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O8 - Dementia and Alzheimer’s Disease
31 października 201632 minFind out what medical scientists mean by "dementia," which results from disease and is not a normal part of healthy aging. The most prominent disease that causes dementia is Alzheimer's, so Professor Polk walks you through its history, symptoms, and palliative treatments, as well as the current state of Alzheimer's research.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O9 - Parkinson’s Disease and Stroke
31 października 201632 minContinue your study of age-related brain diseases with an investigation of Parkinson's disease and stroke. What are they? How do they affect a person's behavior? And can they be treated? Examinations of these questions and more take you through neurochemistry, stem cell research, and strategies you can use to reduce your risk.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O10 - Aging Well: Staying Active
31 października 201634 minGet ready for good news to help stave off mental decline! Here, you'll analyze the effects of physical, social, and mental activity on the aging brain. Ample evidence from communities with longer-than-average lifespans shows that getting plenty of exercise and maintaining a vibrant social life can help keep the mind sharp and the spirit young.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O11 - Aging Well: Diet and Stress
31 października 201630 minShift your attention from the effects of physical and social activity to the impact of diet and stress. Explore the benefits of a diet rich in fruits, vegetables, and omega-3 fatty acids and low in processed foods - like the Mediterranean, DASH, and MIND diets. Then, delve into the physiological effects of stress, trace the damage it creates, and learn how to reduce stress to increase longevity.Bezpłatny okres próbny kanału The Great Courses Living lub zakupS1 O12 - The Science of Immortality
31 października 201635 minIs it possible to live forever? Would we even want to? Conclude with a look at cutting-edge research involving gene therapy and stem cells that may help us mitigate or even "cure" the effects of aging. The science is still emerging, but the possibilities are fascinating.Bezpłatny okres próbny kanału The Great Courses Living lub zakup
