What is the CEO of brains?

Excuse me, could you elaborate on the term "CEO of brains"? It seems a bit unconventional, as typically, the Chief Executive Officer (CEO) is a leadership position in a company or organization. Are you referring to a metaphorical sense, where someone is considered the leader or mastermind behind a group or project? Or is there a specific company or organization named "Brains" that you're inquiring about? If it's the latter, I'm not familiar with the entity, but perhaps you could provide more context. In any case, I'm curious to understand your question further.
