Remember the sci-fi movie Inception? The whole plot was based on the concept of planting a thought into someone's mind. You might be surprised to hear it's not all fiction--scientists have been studying the concept of placings ideas and experiences into a person's mind without their knowledge through neurofeedback.
The technique utilizes an fMRI machine as a means to track and tell a person what's going on in their brain. While there are different versions of the technique, Associative Decoded fMRI Neurofeedback is the closest thing to inception. It combines the fMRI machine with brain scanning and has made it possible to teach a subject new skills and associations without their knowledge. This interesting technique, developed by Takeo Watanabe of Brown University and partners at the Advanced Telecommunications Research Institute in Japan, has shown promising results with long-lasting effects.
It may sound sinister but Associative Decoded fMRI Neurofeedback is actually being developed for a good cause. Their hope is to eventually be able to treat neurological and psychiatric disorders. With more research, Watanbee's version of neurofeedback may serve to be a powerful tool for mental health in the future.
