@icedquinn @lanodan I forget which lobe; it detects something familiar, and then inhibits the novelty-seeking behavior. Allegedly, you cut up that lobe in a cat and the cat remains in exploration mode. Anyway, that lobe runs low on glucose, can't push the other lobe down. (I cannot remember which part of whats was mashing the other one down; maybe there's a neurobiochemist or close enough. I think a hippocampus was there, or was at least watching the other two.)
