Video summary
This short film looks at how humans perceive the world and how our brain creates an image of what is around us. A real-life example of a blind climber who uses his tongue to see is shown.
How does your brain create an image of what is around you?
Combining 3D CGI graphics with a real life story, this short film questions what 'sight' really is and where it happens.
What we see is a picture created by our brain based on nerve impulses from our eye.
The story unfolds to show a man who has been blind for 25 years who can now 'see' well enough to climb.
This is a result of a new piece of technology that turns electrical data from a camera into impulses sensed by his tongue.
Using this bit of kit, we seem him climbing and playing with his children.
This short film is from the 成人快手 series, Inside the Human Body.
Teacher Notes
Students could use this short film to explore the role of the brain in sight.
It could be used to stimulate class discussion as well as talking about the way the nervous system can adapt.
It is also a great example of 'how science works', putting the technology development in context.
This short film will be relevant for teaching biology at KS3 and KS4/GCSE in England, Wales and Northern Ireland and National 4/5 in Scotland. Appears in AQA, OCR, EDEXCEL, CCEA, WJEC, SQA
