Context-Dependent Correlations (aka PsychoPhysiological Interactions)

As promised, here is the tutorial on context-dependent correlations. Just to confuse you a little, I also refer to them as psychophysiological interactions, or PPIs, because different people call it different things. Kind of like how some people call me Andy, but other people call me Andy Pandy. Specifically, my mom.

More details about PPIs - and my childhood - coming up soon, but first I have a level 2 scanning emergency to take care of tonight. And I mean that in all seriousness, not the way I usually toss that phrase around - to get out of awkward dates. And now you know, ladies!
