Sure! Unfortunately, it was purely a joke and has no helpful qualities that I can think of.

Your prefrontal cortex is the very front edge of your brain, and it's (very generally because brains are complicated) responsible for problem solving, decision making and stuff like that.
It's the part of your brain that makes the call to actually remove the blanket.
These are called "executive functions".

It's also very associated with a lot of parts of personality expression, so while it's not where "you" are, damage to it has a more pronounced impact than other parts of your brain, so sometimes people treat it like it's "you".

It picks which tasks to do based on that reward system I mentioned in my original comment. It doesn't directly control which task it's pointed at trying to solve, so it can come up with a plan to do what's needed, and then discover that the first step is "bad" and it should keep doing what it's doing.

That's the little man sitting at a desk who knows it's all fucked. Did all the work and then was directed to ignore it, knowing that was the wrong call. Something else is in charge of that reward process (kinda), and you can't "reason" with that process.
