Le mélange des sens

S1 E5
·
2019

The brain contains just over 100 billion neurons, each of which can form up to 10,000 connections. It takes such a network to process the flow of information sent by the body's sensory receptors. Because at every moment of existence, all your senses are solicited. Life is multisensory. Sight, touch, hearing, taste, and smell send sensory messages at a speed of 430km/h to the brain. This continuous flow of information is sorted, analyzed by the brain which directs the senses, organizes them and improves them without the help of any technological intervention. Its plasticity, which we are just beginning to understand, allows it to adapt constantly. If you lose a sense for example, the brain reorganizes itself. It increases the others. Like this blind man, able to paint pictures of which he perceives the colors with his fingers... But the brain can also decide to beat time differently, to orchestrate the senses in an original way. This is what happens to synesthetes, people who always associate two or more senses, or even have a real power: the ability to feel the pain of others...

Thanks to digital technologies, scientists who study the sense of sight are taking us into a new era! They are now able to explain some rare phenomena such as the case of a person who can see 99 million more colors than people with normal human vision, or to restore sight to someone who had lost it. It is biotechnology and digital…

E3 : L'ouïe

48min36s
As the mysteries of hearing begin to unfold, technology and scientific research are cooperating to restore, replace or augment this extremely powerful human sense. Hearing endows some individuals with super powers... Like this young man whose hearing is almost absolute, capable of turning every sound into music. Or this blind man who…

E4 : Le goût et l'odorat

48min36s
Smell... as natural as breathing. 16 times a minute you inhale air that passes through your nose and fills your lungs. Billions of molecules travel through your nasal passage and are captured by the cells of your olfactory organ. But you think you don't have a great nose... Your sense of olfaction is however much more developed…
