Dream Recording: Brain Imaging Will Reveal The Movies In Our Mind

Have you ever dreamed of remembering the dreams you had last night? Well, in the near future we will have the ability to record our dreams for us to rewatch later. The researchers from the Gallant Lab at University of California, Berkley made this possible using functional Magnetic Resonance Imaging (fMRI) and other computational models where our visual experiences are recorded and decoded using our brain activity and reconstructed to video clips.

Here's a sample video where the test subject was watching video clips (left) with the result images (right): 

This is brilliant!!!1 How is it done? Can you tell me? Can you tell me?

The magic starts at the intersection.
The technology uses our brain activity - how our brain responds to what we see, via our neural signals. Instead of using cognition which is far more complex than studying a more concentrated area, they have focused on vision and how it sends information to our brain.

This does not only apply to images we see through our eyes but also to imageries our minds create. One common example would be the flashbacks of the past, our memories. This technology would also make it possible to record our dreams. You never had to worry about forgetting the good dream you had last night. The nightmares, though.

Then, the resulting images will be gathered from a library of 18 million seconds of random YouTube videos. So it's not actually revealing the exact images from our minds but will search for the most similar look-a-like from YouTube.

This is great breakthrough, indeed. This technology can be of many uses. For the those who cannot speak or express their thoughts verbally like a stroke victim, or a person in a coma, this is of great use. It is also possible for people with paralysis, cerebral palsy, and similar disabilities, to use this to communicate to either another person or a computing device.

What do you think of this technology? Would there be more good use of this than the opposite? And would you prefer to have the ability to record your dreams? What else do you think can this technology be of use? Feel free to share your thoughts below (by typing of course, we're not into this technology yet. But soon...)
