Amazing video shows us the actual movies that play inside our mind
By Alasdair Wilkins
This is about as awesome as neuroscience gets. This video shows us some everyday clips, and - thanks to some super-advanced brain imaging and computer simulations - how those clips are seen inside our brains.
Researchers at UC Berkeley used functional magnetic resonance imaging (fMRI) and some seriously complex computational models to figure out what images our minds create when presented with movie and TV clips. So far, the process is only able to reconstruct the neural equivalents of things people have already seen, but eventually it might be possible to construct the images people see in dreams and memories.
This could also open up new ways to communicate with those whose speech is severely impaired, such as stroke victims, patients with neurological diseases, and even people in comas. It's probably worth stressing that we're decades away from using this tech to read people's thoughts and intentions, just in case that's something you're worried about.
