My dictionary says “cerebral” means “Of or relating to the brain or cerebrum”. But this definition doesn’t seem to fit in the contexts I read or found in the internet, such as:
“Mirror, mirror on the wall, who among us is fairest of all?” she said.
Bianca straightened up and listened, as if the mirror might answer. If it did, it was in a pitch too cerebral or too hushed for Bianca to hear.
He currently does most of his concert appearances in shopping malls, so the music is definitely not intended to startle or to be too cerebral.
It sounds to me that “too cerebral” means “too difficult”. :?
