The brains went to my head?

No, it's not in common or everyday usage. I've never ever heard that particular expression. In general, if something "goes to your head", it means you start noticing it more, asigning greater importance to it, maybe having it start affecting all yoour actions, making it overly important in your decision-making, losing your sense of perspective. Keep in mind that song lyrics are often pretty opaque, as to exactly what the writer may be trying to convey. I'd say here it means the person thinks he's smarter than he really is and has done something really dumb as a consequence (don't know what's going on in the rest of the song). Your friend's "proud or arrogant" fits too.

So the point is that the expression is not the one used in your daily lives. Had I talked to my brain 'Your brain went to your head,' he must have responded 'What the heck are you talking about?'. Thanks a lot for your useful explanation.

When you look at the lyrics of pop songs for their meaning or for clearly understood diction or even every-day language, you'll be disappointed or misled. It is poetry at its base. Sometimes popular music uses humor or any words that fit into the rhyming scheme for convenience. The phrase 'Brains going to someone's head' is intended as ironic humor.

As was written before, this phrase means someone's opinion of their own intelligence has gotten out of proportion. 'Going to your head' implies conceit.

I agree.

I think its a poetic twisting of language
intended to mean that he was overly impressed
with the strength of his intellect. Members of Mensa r sometimes accused of that.
