more from the discussion:
"it turns out, actually, that our brains are constructing representations for all the possible actions with all the possible objects in front of us and then tamping them down. You can see this in patients who have lost some inhibitory controls because they’ve had damage to their frontal lobes. You get what’s called utilization behaviors. You get people who, literally anytime you put a comb in front of them, will start combing their hair just because there’s a comb. They’ll use it. If you put a glass in front of them they’ll drink from it.

I think that’s probably also true of our emotional responses. There’s much more being generated and then tamped down. So one really important function our brain provides us is the ability to not act on all the possibilities that it’s generating."
interesting.
