I wonder if this could have some great research applications. A year ago I watched some lectures from Stanford on ethobiology (i.e. the branch dealing with the biological processes underlying behavior) on YouTube by Robert Sapolsky, and he talked a lot about the difficulty of figuring out what parts of the brain (and which interplays of brain centers) are responsible for behavioral patterns, especially when it comes to the more complex things. One joke was something like: "You know that feeling when someone calls you and you don't really want to talk, but feel uncomfortable with saying that actually you're busy and would rather just read a book than talk? I think we've found the brain center for that." We have learned a lot from what happens when people have certain parts of their brains damaged. But maybe we could learn much, much more about the brain by being able to fiddle around with many different kinds of signals to different brain centers, and trying out hypotheses by stimulating several centers simultaneously in order to produce (or not produce) certain behaviors?
