A video clip that caught my attention

Could We Record Our Dreams?

Short summary
This video clip talks about how our brain works when we are dreaming and using this how scientist found out a way to record our dreams. Scientist created a technique using the functional MRI Scanner. The subjects were shown pictures made up of pixels and the softwares finds a pattern in the brain activity through the MRI. And after a enough data different pictures were shown to the subjects and the result from the pattern of the brain came out to be quite the same but very blurry. Scientist even woke subjects up while they are sleeping in the MRI and find the pattern. They did this 200 times to different and they were able to match some of the stuff to the dreamers description. There is also a study where scientist show the subject a long footage and monitor the brain activity after that. By looking at the results of these study, it shows that there is a possibility that in future we would be able to find more clues and maybe eventually find out why we dream.
What I have learnt
  1. I have learnt that more about the some of the similarity and difference of brain and radio waves and also learnt more of what are they.
  2. I learnt that by using the MRI scanner to find out the brain wave and brain activity, we can also find out what the person saw or what the brain is doing or even know what the brain is thinking but in a very blurry manner.
  3. I also learnt more about how the human brain works and that different part of the brain are active for different activities, instead of the whole brain being active all the time.
