Your original text contains instructions about captions naming functions rather than lobes themselves, and how to distribute these captions across buttons. Here is a corrected and clearer version:
"The captions will name the functions of the lobes, such as vision, language, balance, etc., rather than naming the lobes themselves (as described in the text file). There can be multiple captions, with each lobe covering several buttons, except for the occipital lobe and the cerebellum, which may each have only one button. Next to the captions, include fun characters that illustrate the respective functions."
Key improvements include clearer sentence structure, consistent tense usage, and smoother flow.
