Can we read someone’s mind and control behavior? This question may sound like something from science fiction and far from reality; however, it may be closer than we expect. All human activities, such as feelings, thoughts, and behaviors, are generated by networks of electrical signaling among neurons in the brain. If we could fully understand these neural activities, it might become possible to interpret our thoughts from outside and even intentionally modify those states by interfering with neural signals. 

One potential method for achieving this is brain-computer interface (BCI) technology. Traditionally, BCIs required invasive neurosurgery to implant microelectrode arrays into the brain. However, non-invasive techniques such as functional magnetic resonance imaging (fMRI) have been developed and offer safer alternatives for interpreting brain activity, increasing the possibility of decoding human thoughts and intentions.

Some technologies have been developed to support people with disabilities. Real-time encoding and decoding of brain activity allow speech-impaired patients to communicate without speech or physical movements. Once fully realized, some disabilities may no longer limit patients as they do today. While BCI may bring hope to the medical field there are potential risks, including the erosion of mental privacy, unequal access to cognitive advantages, and the potential undermining of the value of achievements.

This poster will discuss how reading minds and controlling others will be technologically possible, as well as the potential benefits and risks.
