下丘腦

下 = 一 + 卜 : Mnemonic symbol: from the up/down logic, and a little bit the shape of the character, a ladder.

Xi Shi (xi) is on a retreat in the ashram. Using a voodoo staff (卜), she divined that next (下) week she'll have to play the flute (一) sixteen hours per day. Because she hates playing the flute, she climbs over the ashram's bathroom (a4) wall using a ladder (下) to escape.

丘 = 丿 + 丨 + 工 : In front of the outhouse, the Queen of Hearts set up a mound for her relatives. She also put a gate in front of it where the two pillars are a banana and a dinosaur bone respectively, and the horizontal beam is a steel beam.

脑 = 亠 + 凶 + 月 : Napoleon and the moon lost their minds in the aorta and put their brains in the middle of the room. Now they're dancing around their brains in a weird ceremony. The moon put on a vicious demon mask and Napoleon is wearing a way too large beret while they dance around their brains.
