Homeostasis refers to the body’s ability to maintain a stable internal environment, and maintaining homeostasis requires that the body continuously monitors its internal conditions. From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point. Topics covered include homeostasis, negative feedback loop, nervous system, endocrine system, digestive system, excretory system, musculoskeletal system, and the immune system. Part of the "Biology" 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.
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.
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.
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.
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.
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.
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.
Dr. Kimberly Dodge became deaf at the age of eight. She knew she wanted to work with animals by the time she was in eighth grade. Today she is an emergency veterinarian at the Connecticut Veterinary Center. This is a short segment from the "Achieving Goals! Career Stories of Individuals Who Are Deaf and Hard of Hearing: Phenomenal Professionals."
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.”
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.
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.
