Using technology to hack your brain

Could technology be used to control your brain? In a video created by ASAP Science, they say by using light as an input source to pinpoint locations on the brain, you can activate parts of the brain that control movement, and feelings.

Clearly, this is just the high level explanation. Watch the video for the details. It’s mind-blowing what could potentially be done here. It’s similar to Moran Cerf, who is a neuroscientist who has shown how to project patients’ thoughts onto a screen in front of their eyes.
