How do our brains generate consciousness? We take it for granted that the brain makes being alive feel the way it does, but there's no reason why it should. The brain is made of the same biological ingredients as the rest of the body, and yet somehow it manages to generate the indescribable phenomenon of consciousness.
The changes in the brain during the growth and development of a baby into an adult are explored. Susan Greenfield looks at how little of the fine structure of our brains is predetermined at birth, how the connections between nerves are constantly changing in response to what we encounter in the outside world. She explains her view that learning, memory and even the process of becoming a unique individual, should all be seen as a restless brain adapting minute by minute to the environment it encounters. Life is about how the world leaves its mark on us.
Science Bank is a series of programs that demonstrate a variety of science experiments with graphical explanations and real life applications. Today: A combination of dissections, demonstrations and graphics offer an insight into the structure of key body parts that is almost impossible to achieve in the classroom.
What is it about the brain that has put us in charge of the planet? Were has the human unique linguistic abilities come from? Are there special structures in our brains which no other animals possess? Or is it possible that our sophisticated rich cultures are merely the result of having larger brains? Susan Greenfield explains why she believes we are truly just big brained chimps.
Science Bank is a series of programs that demonstrate a variety of science experiments with graphical explanations and real life applications. Today: This program explores the human digestive system. It demonstrates the experimental procedure for testing and identifying the four main food types. Practical investigation explains the activity of digestive enzymes and the processes involved in breaking down food. Graphics, x-rays and endoscopic photography examine the structure of the digestive system.
The illusion of vision. It feels as though we open our eyes and just see what's out there, but the more we learn about the brain's visual system, the further it seems this is from the truth. Patients, who can't see movement or recognise faces, reveal the tricks and short cuts the brain uses to construct an illusion of reality. Is the brain making up so much of what we think we're seeing that vision is really just dreaming with your eyes open?
Susan Greenfield explains why she believes all aspects of human experience will eventually be explained in terms of the physical processes of the brain. The story of how we have gradually come to understand the astonishing complexity of the brain is revealed, from the earliest crude studies of the effects of brain injury, through to the latest insights from direct stimulation of specific areas in patients undergoing brain surgery whilst wide awake. Is it possible that our most spiritual feelings are merely the result of electrical activity in the temporal lobe?
Science Bank is a series of programs that demonstrate a variety of science experiments with graphical explanations and real life applications. Today: A practical examination of thermal energy and its physical effect on solids, liquids and gases. Graphics illustrate the kinetic theory and help explain the physical processes taking place.
Where do emotions come from? Why do they feel so different from thoughts? Is the answer in the biochemistry of the brain and all the hundreds of chemical neurotransmitters which bathe the nerves?
Science Bank is a series of programs that demonstrate a variety of science experiments with graphical explanations and real life applications. Today: Current, voltage and resistance are all related. This relationship is explored qualitatively and quantitatively through practical investigation. Graphics help explain the observed phenomena.
Science Bank is a series of programs that demonstrate a variety of science experiments with graphical explanations and real life applications.
Science Bank is a series of programs that demonstrate a variety of science experiments with graphical explanations and real life applications. Today: Atomic structure is an abstract concept. This graphical exploration of the order and arrangement of subatomic particles illustrates the theory in a way that is normally unachievable in the classroom.
This week, Sex In The Bush explores the really fun bit - copulation. Combining stunning footage with entertaining stories from scientists who have dedicated their lives to the study of animal sex. Episode Two reveals extraordinarily intimate details of what occurs during sexual intercourse.
Cancer threatening the existence of the Tasmanian Devil; The Royal Botanic Gardens - Australia's oldest research institution; Sand - to squeak or not to squeak, that is the question.
The Arctic winter storms sweep over at more than 100km/h over the ice with temperatures dropping down to -60 degrees C. In this inhospitable world lies a nursery of polar bears, ringed seals, walruses and belugas. Thomas Behrend and his team follow two polar bear families over one year capturing rare and unique pictures of a polar bear mother and her triplets. Polar Bears: Living on Thin Ice shows the beauty of the Arctic as well as the unique behaviour of its inhabitants, and their struggle against the negative forces of climate change.
Dr Maryanne Demasi investigates the bitter truth about the dangers of a sweet diet and Ruben Meerman takes a look at how fluoride protects teeth and the reasons for its addition to water supplies.
The story of the number 1 is the story of Western civilisation. Terry Jones, of Monty Python fame, goes on a humour-filled journey to discover just what an amazing tale lies behind the simplest number we have. Using Pythonesque computer graphics, 1 is brought to life in all its various guises.
