The smartest people in the world have spent millions of dollars trying to develop high-tech robots. Even though technology has come a long way, these humanoid robots are nowhere close to having the "brain" and motor control of a human. Why is that? A MIT scientist explains the motor control processes in the human brain, and how cutting-edge research is trying to implement it in robots. Part of the "Science Out Loud" series.

Host Emily Graslie travels to the Denver Museum of Nature & Science, and she explores the health sciences collection. Dr. Nicole Garneau is the curator for the exhibit, and Graslie becomes the newest addition to the DNA collection. Part of "The Brain Scoop" series. Please note: This title shows donated human anatomy to the museum collection.
While the human brain and nervous system are wired with hundreds of billions of nerve cells, or neurons, sea slugs can get by with tens of thousands. Ironically, sea slugs reveal a lot about the chemistry of the human brain and nervous system. In fact, they are ideal as study subjects for research on learning, memory, and how neurons control behavior. With support from the National Science Foundation, analytical chemist Jonathan Sweedler and his team at the University of Illinois are working to develop new measurement tools that enable insights into the function of individual cells in the central nervous systems of slugs and other animals in order to uncover novel neurochemical pathways. Part of the National Science Foundation Series “Science Nation.”
In this episode, host Emily Graslie meets with Dr. Robert Martin to discuss the evolution of human birth. They also highlight the progress being made to reduce mortality rates related to giving birth. Part of "The Brain Scoop" series.

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.
Drug addiction is a disease of the brain, and teens are at the highest risk for acquiring this disease. Stephen Dewey and other leading scientists detail how drugs like heroin, nicotine, cocaine, and marijuana change the brain by altering the way it registers pleasure. Young recovering addicts describe how addiction involves intense craving for a drug and loss of control over its use.
In many ways our brains may be like those of animals, but in our capacity to think, to remember, and to create we are much different. Looks at some of the reasons for these differences, exploring the neural structure of the human brain, our physiological brain capacity, and the use of memory and symbols.
Sagittal, or side view of the human brain shows the different lobes of the cerebral cortex. The frontal lobe is at the front center of the brain. The parietal lobe is at the top back part of the brain. The occipital lobe is at the back of the brain, and the temporal lobe is at the bottom center of the brain. The motor cortex is the back of the frontal lobe, and the olfactory bulb is the bottom part. The somatosensory cortex is the front part of the parietal lobe. The brainstem is beneath the temporal lobe, and the cerebellum is beneath the occipital lobe.

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.
Researchers around the world can compare notes on one of the most powerful tools available for imaging human brain function, the fMRI, thanks to support from the National Science Foundation (NSF). The project, called OpenfMRI, allows scientists to share their data easily and securely in a standardized format. The advantages are clear to Stanford neuroscientist Vinod Menon, who researches brain development and is using OpenfMRI to validate his research. Menon says as more studies are added to OpenfMRI, it becomes a powerful tool for diagnosing and treating neurological disorders. Part of the National Science Foundation Series “Science Nation.”
The human brain is often compared to a computer, but this three-pound organ is far more complex, powerful, and capable than the most advanced computer. Everything we do, are, think, and feel begins with the brain. Defines the parts and functions of a brain cell, explores how the brain works, and mentions brain chemicals.
The human brain is wired to perceive patterns and structure in surrounding environments. Young children especially need structure to feel secure. Yet the developing brain is also continuously seeking new information. Discover how to give young children the structure they need to establish a strong foundation for continual learning. Part of "The Brain" series.
Dr. Marian Diamond was a pioneering scientist and educator and considered one of the founders of modern neuroscience. At the University of California, Berkeley, she and her team were the first to publish evidence that the brain can change with experience and improve with enrichment, what is now called neuroplasticity. This documentary follows Dr. Diamond over a 5-year period and introduces the viewer to her many scientific accomplishments.
What happens in your brain when you get lost or forget something? Johns Hopkins University Neuroscientist Amy Shelton believes she can find the answer. With funding from the National Science Foundation, she’s testing human spatial recognition. Study subjects learn and recall their way around a virtual maze while an MRI scans their brains. By analyzing MRI images of blood flow in the human, Shelton can get a picture of how the brain learns and recalls the spatial world outside the body. By understanding those processes, she believes she can develop techniques that will help improve human memory.
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.”
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.
Sight, touch, hearing, taste, and smell send sensory messages to the brain at a speed of 430km/hr. The brain deals with 11 million information signals per second, and this continual flow of information is sorted and analyzed by the brain, which directs the senses, organizes them, and improves them. The brain’s plasticity allows it to continually adapt. If and individual loses one sense, the brain reorganizes and compensates by increasing the power of the other senses. This episode highlights an artist who is blind and uses his fingers to feel the color of the paint before applying it to the canvas. Part of the “Human + The Future of Our Senses” series.
Paleontologists have studied the fossil record of human evolution just like they have done for other major transitions, including the evolution of tetrapods from fish and the evolution of birds from dinosaurs. Sean Carroll and Tim White discuss the most important human fossils and how they illuminate key phases of human evolution, focusing in particular on three traits: larger brains, tool use, and bipedality.
Touch, taste, smell, hearing, and sight: the human body's five major senses. They are senses that have evolved independently over millions of years but are brought together by our marvelous central nervous system into the most refined way of interacting with the environment of any species on the planet. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of each of these sensory systems and shows how the brain uses them to produce what we call being human.
