Neurobiology tells us that when we think or feel, a host of neurons in our brains fire electrical signals. It turns out that certain thoughts—like wishing an object to move spatially—and certain emotions, have electrical signatures that can be identified by external sensors attached to our heads. This discovery is not new. What is new is an inexpensive headset from Emotiv Systems that can "read our minds" and issue commands to machines. Check out the video below and ponder both the positive and negative possibilities of this technology.
