Thought control? How would you like to be able to turn on your television just by thinking? Or have the door to your house open by mind power when your hands were full? This isn't something that will remain science fiction for long. The technology necessary to make this happen is here now. First of all, you have basic thought control now, meaning you can control and direct your thoughts. You can imagine a friend talking in your mind, for example. Then you can choose to hear music in your imagination. If you are hooked up to an electroencephalograph when you do these things, it will also be clear that these two thoughts are handled in different parts of your brain. This electroencephalogram, or EEG, is important, because what we can measure, we can use to do things. Think about this for a moment. Modern electronics has made it possible to easily operate things as a response to measurement. A thermostat measures the temperature, for example, and turns the heater on or off according to that measurement. Security lights turn themselves on when light levels get low. Thought Control Devices We can already measure and track what is going on in the brain. Is it inconceivable then, to have that measurement automatically trigger some action? For example, even before the electrical patterns of the brain were made "visible," we measured pulse rate with many different machines. Now, what if instead of sending a signal to a monitor telling a red light to go on when the heart raced, the signal told the TV to turn on? Think of anything that gets your heart racing and the TV would turn on, right? Call it mind power, thought control or whatever. You can see that such a device has been possible for at least a generation now. With new technology, and more detailed measurements of the actual electric patterns of the brain, how much more is possible? Someday, an electroencephalograph type of device will be able to more directly read your mind. The technology will eventually get to the point where it can print out the actual words you are thinking. We are a long way from that, but we are right at the brink of building machines that give us thought control of the things around us. You see, even with the crude measurements being done now, as long as we can choose what to think about, and any resulting change in the brain can be measured, the possibilities are endless. For example, we can already see the changes in the brain when a person thinks about music, versus a conversation. An existing electroencephalograph machine, using electrodes attached to your head, could be set to turn on the lights instead of producing a changing chart when you sing in your mind. For paraplegics without speech, there's real hope in this idea. A patterned alternating of thoughts could be used as a sort of Morse code, spelling out words on a screen. They could actually use thought control to make a message appear! At the current level of technology, this would be a tedious process, but the amazing thing is that all the necessary things to build a machine like this are here right now. It's time for thought control!
