If you are interested in what researchers are working on when it comes to using brain scanning this video from Nature Video (2013) shows three interesting example of how brain scanning can be used for:
- Reconstructing what you see based on fMRI
- Trying to visualize your dreams based on brain activity during sleep
- Developing a tool for detectives to detecting if you have been a specific place or seen a specific person based on your brain activity.
Read the original Nature Article or visit Jack L. Gallant project page for some of the research behind.
While there is a gap from research to everyday application many applications are already out there using EEG technology. See for instance “Mindball” – a game where the winner is the one who is able to relax the most (least brain activity) or “Muse” a wearable device that will help you meditate.
