This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Falls are a major public health threat among older adults Exercise interventions are one of the most effective ways to prevent falls in the community But these interventions depend on early identification of those at high risk for falling One useful tool physiotherapists can use to spot vulnerable individuals is gait speed A gait speed under 1.0 m/sec has been well correlated with an increased fall risk in the elderly Now, researchers have shown that using a gait-speed cut-off of 1.0 m/sec captures several other modifiable risk factors for falls including a multiple-fall history, depressive symptoms, and a high number of medications The results support gait speed assessment as an interdisciplinary single test to identify individuals who would benefit from guided fall-preventive exercise Kyrdalen, et al. Associations between gait speed and well-known fall-risk factors amongst community-dwelling older adults..."

The most recent knowledge of the anatomy, physiology, biochemistry, biophysics, and bioengineering of the gastrointestinal tract and the associated pancreatic, liver and biliary tract systems is presented and discussed. Gross and microscopic pathology and the clinical aspects of important gastroenterological diseases are then presented, with emphasis on integrating the molecular, cellular and pathophysiological aspects of the disease processes to their related symptoms and signs.

An integrated course stressing the principles of biology. Life processes are examined primarily at the organismal and population levels. Intended for students majoring in biology or for non-majors who wish to take advanced biology courses.

Research has changed our concepts of brain organization and provided dramatic evidence showing far greater similarities between brains of birds and brains of all mammals. Harvey Karten explores what goes on inside a birdŐs brain. Learn how brains of birds compare to those of humans and other mammals and find out what the study of birdŐs brains can teach us about the nature and origins of human brains. (57 minutes)

UCSD Cognitive scientist Joan Stiles reveals the latest understandings about the intricate relationship between biology and external influences in the development of the brain. (58 minutes)

What are the mechanisms by which neurons differentiate to achieve the spectacular complexity of the brain? Join UCSD's Nick Spitzer as he explains what we know about this process. (57 minutes)

Join UCSD's Larry Squire in a fascinating presentation of recent research about memory systems in humans and other mammals. (58 minutes)

We make thousands of decisions every day: where to go, what to do, when to do it. Join UCSD's William Kristan and discover how neurons, synapses, and chemical input play out in decision making. (57 minutes)

Neuroscientist Patricia Churchland explores how the human mind functions in guiding one's decisions. (55 minutes)

In this fascinating presentation, The Salk Institute's Terry Sejnowski explores how by its nature the human brain is susceptible to the effects of addictive substances. (59 minutes)

In this edition of "Grey Matters," Aniruddh Patel, of the Neurosciences Institute, discusses what music can teach us about the brain, and what brain science, in turn, can reveal about music. (51 minutes)

Join Stuart Lipton of The Burnham Institute and discover important anti-aging strategies, the latest drugs for degenerative disorders such as AlzheimerŐs disease and the potential use of human stem cells for neurological conditions. (57 minutes)

UCSD's Charles Zuker explores the neurobiology of taste, smell and vision. (88 minutes)

Is sleep for rest? To conserve energy? For development? To cool the brain? To warm it? To boost the immune system? To learn and memorize? Or to unlearn, ridding our brains of excess mental baggage? All of these ideas have been proposed, leading to the suggestion that insomniacs might do better to count sleep theories instead of sheep. Join renowned neuroscientist Ralph Greenspan of The Neurosciences Institute to explore the latest research into the question of why we sleep. (59 minutes)

During the past decade, there have been dramatic advancements in the brain and cognitive sciences. For the first time, understanding how the brain works has become a scientifically achievable goal. In this new lecture series, Grey Matters: Molecules to Mind, San Diego's leading Neuroscientists explore the human brain. The first lecture in this series addresses an issue that has often been absent in these discussions: what role do stem cells play in development of the brain? (59 minutes)

UCSD cognitive scientist Martin Sereno takes you on a captivating exploration of the brain's structure and function as revealed through investigations with new advanced imaging techniques and understandings of evolution. (57 minutes)

Why are humans the only species to have language? Is there something special about our brains? Are there genes that have evolved for language? In this talk, Jeff Elman, UCSD professor of cognitive science and co-director of the Kavli Institute for Brain and Mind, discusses some of the exciting new research that helps us understand what it is about human language that is so different from other animals' communication systems, and what about our biology might make language possible. (58 minutes)

The National Center of Excellence in Women's Health and Osher Center for Integrative Medicine at UC San Francisco present lectures to provide practical, easy ways to be proactive with your health. In this episode, Susan Folkman, Director of The UCSF Osher Center, talks about learning ways to manage and cope with stress. (44 minutes)
