Reading Brain Activity

It is nice to know that I can tell my brain to turn on a television, change channels and then switch on my computer notebook just lying in my bed. This new Hitachi technology called optical topography, can send a small amount of infrared light through my brain surface to map out changes in my blood flow. Fun to know that one has a power to move things around just by thinking about it. The trouble is this brain-machine interface device is too big and cumbersome to put on your head. But Hitachi technologist promises us that the new lighter model, a kind of headband, will soon come out for general marketing. Life is going to be fun for the kids when they can move toys around by simply thinking. The headband is much better than the the idea of implanting of a chip under the skull, which requires a brain operation.
