If everything is going the way that it's supposed to be going, the only pieces of your brain that you can actually see are the terminuses (termini?) of your optic nerves deep inside your eyeballs. And that's probably for the best, because brains aren't designed to be seen. Even if you somehow could see your brain, it wouldn't look nearly as cool as this visualization of what's going on inside, created by the Neuroscape Lab at UCSD.
I'd tell you what the video below shows, but I'd just make a hash of it, so here's what the researchers say:
This is an anatomically-realistic 3D brain visualization depicting real-time source-localized activity (power and “effective” connectivity) from EEG (electroencephalographic) signals. Each color represents source power and connectivity in a different frequency band (theta, alpha, beta, gamma) and the golden lines are white matter anatomical fiber tracts. Estimated information transfer between brain regions is visualized as pulses of light flowing along the fiber tracts connecting the regions.
After you get your brain scanned on an MRI machine, you put on an electroencephalograph, which is one of those hats with a bunch of electrodes in it that can measure brain activity. Then, you can watch on a monitor as the patterns of brain juice ebb and flow depending on what you're doing. I can only imagine how trippy it is to watch, and I can also only imagine what it looks like on the monitor when you're tripping on something.
