What's Your Philosophy of Controlling the Brain?

As a graduate student, one of the things that stuck with you is that we look for regularities in things. That noise might not actually be noise and might be the signals that are actually of interest. So maybe there's too much noisiness and you would like to help the neural system have the right amount of it or maybe there's not enough. And therefore you have a fixity in your behavior, your perceptions of the world.
