Stem Cells: The Brain's Beginnings
(#9136; 59 minutes; 1/19/2005)
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?
Building the Brain: From Simplicity to Complexity
(#9268; 57 minutes; 3/16/2005)
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.
Perception: Taste, Smell and Vision
(#9269; 88 minutes; 5/18/2005)
UCSD's Charles Zuker explores the neurobiology of taste, smell and vision.
How Do We Predict the Future: Brains, Rewards and Addiction
(#9270; 59 minutes; 6/27/2005)
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.
Sleep, Waking and Arousal
(#9271; 59 minutes; 7/20/2005)
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.
The Origin of the Human Mind: Insights from Brain Imaging and Evolution
(#11186; 57 minutes; 12/21/2005)
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.
Brain Development
(#11188; 58 minutes; 3/22/2006)
UCSD Cognitive scientist Joan Stiles reveals the latest understandings about the intricate relationship between biology and external influences in the development of the brain.
Music and the Mind
(#11189; 51 minutes; 4/19/2006)
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.
Decisions, Responsibility and the Brain
(#11190; 55 minutes; 5/17/2006)
Neuroscientist Patricia Churchland explores how the human mind functions in guiding one's decisions.
Grey Matters: Understanding Language
(#11187; 58 minutes; 7/19/2006)
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.
Decisions: How Do We Animals Decide What To Do?
(#11950; 57 minutes; 12/20/2006)
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.
Conscious and Unconscious Memory Systems of the Mammalian Brain
(#11951; 58 minutes; 1/17/2007)
Join UCSD's Larry Squire in a fascinating presentation of recent research about memory systems in humans and other mammals.
New Drug Treatments and the Future of Stem Cells for the Aging Brain
(#11952; 57 minutes; 3/21/2007)
Join Stuart Lipton of The Burnham Institute and discover important anti-aging strategies, the latest drugs for degenerative disorders such as Alzheimer's disease and the potential use of human stem cells for neurological conditions.
The Science And Fiction of Autism: How To Tell The Difference And Why It Is Important To Do So
(#11953; 59 minutes; 4/18/2007)
What do we know and what do we not know about autism? How can parents, educators and the general public cut through the hype, the unproven and the blatantly bogus? Join renowned autism researcher Laura Schreibman and find out.
Grey Matters: Bird Brains - Pretty Darn Smart
(#11954; 57 minutes; 5/16/2007)
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 bird's brain. Learn how brains of birds compare to those of humans and other mammals and find out what the study of bird's brains can teach us about the nature and origins of human brains.
