With support from the National Science Foundation's Directorate for Social, Behavioral, and Economic Sciences, psychologist Brad Duchaine and his team are studying the brains of 20 people with "face blindness." The team hopes to better understand the computational and neural basis of face processing in general. The research will help scientists develop a classification system for the condition and advance understanding of how different face-processing abilities are organized in the brain. Part of the "Science Nation" series.

Part of the "Branches on the Tree of Life" series. Imagine an animal with no mouth, no digestive system, no excretory or circulatory organs, no brain nor nervous system, and no movement as an adult. In spite of their simple nature, sponges are actually one of the most interesting animal phyla when viewed in developmental, ecological, and evolutionary terms. Clarifies the structure, function, classification, and ecological roles of sponges through animations and time-lapse microscopy.
Peoples’ attitudes about marijuana have changed dramatically over the years, but one thing is certain--marijuana changes the way the brain functions. The THC in marijuana enters the lungs, is absorbed into the bloodstream, and enters the brain almost immediately. Viewers will understand the immediate effects of marijuana use on various body systems. This program also discusses the effects of marijuana on attention, memory, and learning. Part of the "Talk It Out" series.
What happens to the body during sleep? Explores the mystery of REM sleep, shows a computer display of the waves that sweep across the brain during sleep, and presents extraordinary footage of a cat "acting out" its dreams. The analogy of comparing sleep to a ship on automatic pilot graphically illustrates how some functions must and do continue while the conscious brain is asleep.
When the nerve cells of squid suffer an injury, something unexpected happens with the tiny pouches of colored pigment, called chromatophores. A MIT scientist discusses this phenomenon, and how it can be used and modeled on the computer with some surprisingly simple rules. Part of the "Science Out Loud" series.
Military combat, cancer and accidents – all can cause devastating nerve injuries. Sometimes, the body heals on its own. With support from the National Science Foundation, biomedical engineer Christine Schmidt and her team are working to restore nerve function when injuries are more complicated. Surgeons can sometimes move a nerve from one part of a patient’s body to another. Schmidt has developed a method that grafts cadaver tissue onto the damaged area to act as a scaffold for nerves to re-grow themselves.
In this episode, host Jason Silva explores the two hemispheres of the brain. Some of the exercises and activities focus on the way the right and left hemisphere of the brain work together. Part of the "Brain Games Family Edition" series.
Researchers must be aware of three key areas when conducting psychological research: ethics, socially sensitive research, and ethnocentrism. All research must follow ethical guidelines; however, there may be reasons for breaching those guidelines. Viewers will explore how to address research justification and the use of knowledge and interpretation of findings in a socially sensitive research proposal. They will also note how to be aware of social construction and possible ethnocentric biases.
Speech, your means of communication, is the medium for exchanging ideas and expressing both pleasure and pain. Examines the physiology of speech by looking at humans' vocal tracts. Shows how the larynx, vocal chords, wind pipe, tongue, and lips produce the sounds of speech. Also, looks at the ability to understand speech by explaining why your ears and brain can discern the subtle nuances of rapid sounds.
Psychiatrist and author Dr. Norman Doidge travels across North America to meet some of the pioneering researchers who made revolutionary discoveries about the plasticity of the human brain. He also visits with people, once thought to have had incurable brain injuries, who are now living normal lives. Known in scientific circles as "neuroplasticity," this radical new approach to the brain provides an incredible way to bring the human brain back to life.
The eye is one of each human's major sense organs. It gathers light information and transforms it into a signal that is used by the brain to formulate an appropriate response. How does this process work? What are the structures involved, and what do they do? These questions are answered using a unique, integrated approach that combines the anatomy and function of the eye. Includes detailed footage of the dissection of the bovine eye.
The connections between neurons in the brain are involved in everything humans do, and no one’s pattern is the same. Imagine the medical breakthroughs if doctors understood more about the brain’s circuitry. With support from the National Science Foundation, neuroscientist and psychiatrist Karl Deisseroth and his multidisciplinary team at Stanford University have developed a new imaging technology that essentially makes the brain transparent. They can then generate detailed 3-D images that highlight specific neuronal networks. Deisseroth has named this process “CLARITY.” Part of the National Science Foundation Series “Science Nation.”
Explores the strange and relatively unknown world of sleep-a world in which we spend approximately one-third of our lives. Shows how the discovery of REM (Rapid Eye Movement) during our dream period in the early 1950s by Dr. Nathaniel Kleitman at the University of Chicago brought about an understanding of the mechanism of sleep. Before his discovery, it was believed that during sleep the brain was in a state of rest. Also, overviews the nature and frequency of dreams and nightmares, and sleep disorders such as insomnia, apnea, and narcolepsy that affect millions of Americans.
Neuroanatomist Jacopo Annese is looking for 1,000 brains. The Director of the Brain Observatory at the University of California, San Diego is on a quest to collect, dissect, and digitize images of the human brain for the Digital Brain Library, which was launched with support from the National Science Foundation. Annese and his team look for connections, mapping brain structure and connecting it to human behavior. He believes that with a large enough catalog of brains preserved as virtual models, scientists can explore the organ in ways unheard of, revealing new insights into what makes the brain tick.
With support from the National Science Foundation's (NSF) Emerging Frontiers of Research and Innovation (EFRI) program, bioengineer Gert Cauwenberghs, of the Jacobs School of Engineering and the Institute for Neural Computation at the University of California (UC), San Diego, and his colleagues are working to understand how brain circuitry controls how we move. The goal is to develop new technologies to help patients with Parkinson's disease and other debilitating medical conditions navigate the world on their own. Part of the National Science Foundation Series “Science Nation.”
With support from the National Science Foundation, neurologist Ken Paller and his team at Northwestern University are studying the connection between memory and sleep, and the possibilities of boosting memory storage while sleeping. A lot of the evidence has shown that slow-wave sleep is particularly important for some types of memory, and Paller’s goal is to better understand the fundamental brain mechanisms responsible for memory. And that, in turn, may help people with memory problems, including those who find themselves more forgetful as they age. Part of the National Science Foundation Series “Science Nation.”
Tony Ro, a neuroscientist at The City College of New York, is artificially recreating a condition called blindsight in his lab. Blindsight is a condition that some patients experience after having damage to the primary visual cortex in the back of their brains. What happens in these patients is they go cortically blind, yet they can still discriminate visual information. With support from the National Science Foundation, Ro is developing a clearer picture of how other parts of the brain, besides the visual cortex, respond to visual stimuli. He says understanding and mapping those alternative pathways might be the key to new rehabilitative therapies.
Ever wonder what is going on in the mind of a teenager, especially one who is stressed out? UCLA Psychologist Adriana Galvan is on a quest to find out. With support from the National Science Foundation, she’s investigating the effects of daily stress on a teen’s cognition and brain function. She is monitoring the daily stress of teens by having them carry a personal digital device that provides daily measures of stress over two weeks. She is also scanning their brains and measuring their stress hormone levels. By taking this multi-method approach, Galvan is learning how daily stress influences cognitive neurodevelopment in teens.
Takes viewers to an inner city high school where students had serious discipline and learning problems. More than half of the eighth and ninth grade students here were diagnosed with ADHD, and many worked at fourth grade level. The teacher, Allison Cameron, discovered the groundbreaking research by the Harvard Professor of Psychiatry, John J. Ratey, M.D. (author of "Spark: The Revolutionary New Science of Exercise and the Brain"), showing a link between sustained aerobic activity and the brain's ability to grow new cells. Allison also learned that Napierville High School in the Chicago area, which began exercise programs 18 years ago, has one of the best academic records in the U.S.
The ancient city of Rome wasn't built in a day, but now that city, along with all its famous landmarks, can be digitized in just a matter of hours. A new computer program under development at the University of Washington in Seattle combs through hundreds of thousands of tourist photos on Flickr and other photo sharing sites and reconstructs the city – pixel by pixel. Now, viewers can fly around many of Rome's famous landmarks on their computer in far more detail than they'd ever be able to on current virtual map programs such as Google Earth. The new technique may one day create online maps that offer viewers a virtual-reality experience. The software could build cities for video games automatically, instead of doing so by hand.
