BBC Human Senses movie series online is a BBC Natural History Unit production Human Senses movie series | Smell And Taste - we're going to find out how our . India, to pay a visit to some distant relations, a troop of hanuman Langers. In Human Senses, a new six-part series for BBC ONE, Nigel goes in reasons why particular sights, sounds, smells and tastes have such a powerful effect. . out exactly what the body is doing in relation to the outside world. This is a BBC documentary series presented by Nigel Marven, looking at six human senses - smell, taste, hearing, balance, touch, and vision.
Nigel travels to Hawaii to meet an animal which might help unravel why music has such a powerful effect on us. Once a year, hundreds of humpback whales meet up to sing their hearts out. And for us music is all about conveying emotions. In search of the ultimate high, there may be another even more powerful way that sounds can affect us.
Back in England, Nigel watches enthusiastic Status Quo fans who are clearly entranced by the very loud music and discovers why it may be the volume of the music rather than the timeless Status Quo songs that really gets the audience going. Balance Balance is our true sixth sense; it enables us to sense how our bodies are moving around in the world and keep us upright.
There are only two kinds of animal that spend their whole lives performing the tricky balancing act of walking on two legs — humans and some flightless birds, like ostriches. Balancing can be a deceptively complex business. Nigel joins stunt co-ordinator Marc Cass for a dramatic drive and experiences how the balance organs let us know how we're being yanked around, and even turned upside down.
For really fine balance, we need our eyes to help us work out exactly what the body is doing in relation to the outside world. A troupe of acrobats at the Circus School in San Francisco, illustrate this when they perform a human tower with the lights off. Nigel reveals why spinning round in circles makes you dizzy and, under the guidance of Dr Ros Davies from the National Hospital for Neurology and Neurosurgery, discovers why drinking alcohol makes it hard to walk in a straight line.
Our sense of balance is so complex that even if all three components are working fine — the balance organs, the feedback from our limbs, and our eyes — if there there's any disagreement about what's going on, the result can be unpleasant. Dr Frank Golden of the Royal National Lifeboat Institution RNLI explains that sea sickness is caused when the central nervous system receives conflicting messages from the three systems.
The ultimate test for our sense of balance is a trip into space — or even worse, a trip on board the infamous Russian Vomit Comet - a ride so unpleasant that first timers can sometimes end up in hospital on a drip, from excessive vomiting. Nigel gives it a go, at first his brain is deeply confused but gradually he starts to get control of his body again.
It's the ultimate triumph of the human senses - to survive in a situation which no animal was ever designed for. Digital satellite and digital terrestrial viewers will be able to press their red buttons immediately after each episode and put their own senses to the test.
The startling sense of smell found all over your body
Presented by Nigel Marven the challenge invites viewers to solve a series of optical illusions, test their sense of balance, find out whether they are a supertaster or not and find how acute their hearing is. For each right answer viewers will score a point, and will receive personal feedback whether they are right and wrong. If at the end of the quiz they have beaten the threshold score they will be eligible to take the final test and enter the Human Senses competition to win a picture of their own brain taken by an MRI scanner.
The answer to this final test will generate the password viewers will need to enter the competition on the BBCi Science website, www. The Human Senses interactive challenge is the most sophisticated, synchronised channel-switching iTV application yet devised by the BBC.
DCable users will also be able to take the Human Senses Interactive Challenge, in a text and stills based format compatible with the DCable platform. DCable users will be able to enter the competition to win a picture of their own brain using the DCable return path. As with the other platforms, the central theme of the challenge is testing the senses. Additionally, psychometric tests will attempt to predict age from nostalgic smells and determine partner suitability from taste preferences.
Multimedia factfiles will allow users to get to grips with how each of our senses actually works. It offers licence fee payers content across the web, interactive digital TV and mobile devices, whenever, wherever and however they want it. The series producer is Sam Roberts and executive producer is Jessica Cecil.
Presenter Dr John Marsden takes his own sensory journey and experiences the world's most expensive taste, hears a sound that literally makes him feel sick and discovers what it's like to be deprived of all of his senses.
Ripples of sound roll towards us; we spin around and follow a sound wave as it travels into the dark outer ear canal. The senses are our guide to the world, keeping us out of danger and directing us to pleasure. But how sensitive and accurate are they?
And Just how intense a sensation can we bear? On a global assault course for the senses, our chief volunteer must endure many a sensory extreme - from the foulest smell to the hottest chilli pepper, while other, unsuspecting "volunteers" will unwittingly demonstrate just how easily our senses can be misled.
We will also meet the sensory superstar of the animal kingdom, who can help to explain the biological roots of our own senses. Are your eyes being tricked by your brain? Do you know what a supertaster is? Or how to avoid travel sickness? Put your senses to the test in our Senses Challenge.
Discover why food tastes bland if you can't smell. The light hearted but revealing series explores, sense by sense, how they function and why we need them. Then delves so deep At a chilli eating contest, he pushes his taste buds to the limit. The part of the brain where we store memories of any intense emotions we've had smelling that smell.
So the smell triggers a strong feeling based on our previous experiences. It's the exact combination of signals coming from them skin that allows the brain to work out what's touching us.
But our sense of touch does more than just tell us what's there. So like all animals the tastes we crave are determined by what we need. In our case sweet, and salty foods. When bitter or sweet chemicals land on the surface of taste sensing cells, a bitter or a sweet signal is sent to the brain.
Salty and sour chemicals are even smaller. They pass right through the walls of the taste sensing cells.

Once inside they trigger a salty or a sour signal to the brain. But the same food can taste very different to different people. That's because some people are far more sensitive to tastes than others. We've come to San Diego zoo to meet an animal that has a taste for just one kind of food. For breakfast it eucalyptus, for lunch its eucalyptus. For dinner its eucalyptus again. To us it's an incredible boring diet. But it suits the koala just fine.
Koala it's an old aboriginal word which means no drink. Sounds are just tiny movements of the air molecules around us. But our ears contain a wonderful system for detecting these faint ripples in the air. First the sound waves are funneled down the ear cannel to the eardrum. If they were slowed down massively this is what they'd look like. The moving air makes the eardrum vibrate. These vibrations are then amplified by 3 hinged bones. The bones are connected to a tube called the cochlea, which is full of fluid.
The vibrations of the bones send ripples through the fluid, and these ripples move rows of microscopic hair cells. As the hair cells are bent they send nerve signals to the brain, which then works out what the sound is. It's an extraordinary contraption but it works beautifully. We're equipped with a fantastic system for hearing a phenomenal range of sounds.
For that basic information we rely on a set of special balance organs deep within the ear. This series of tubes and chambers no bigger than a pea monitors ever move made by our head. So when we take off, or skid to a halt, or go in to a spin.
These movements are sensed within the inner ear. The tubes are full of fluid. Inside the tubes there are tufts of microscopic hair cells. When we move our heads the fluid move and the hair cells are bent.
