Left is yours. Right is what people call an agent. Tap a part on one side and the matching part lights up on the other, or nothing does.
The brain is a real anatomical surface model, decimated for the web (CC BY 4.0, Agnieszka Starostecka, Wikimedia Commons). It shows roughly where things sit, and nothing about tissue or real size. The comparison itself is an analogy, not a claim that a model has a brain. Some rows have no partner on one side at all, which is the useful part: a loop with a goal and tools is not something you have a single region for.
