Word for a sudden flow of ideas? Is 'brainwave' good enough?

Question

Imagine you are thinking about a problem you need to solve, nothing's coming to mind, and all of a sudden you get a dozen different ideas at once. Is there a word that expresses this ***sudden flow of ideas***? I could only find ***brainwave*** although I'm not sure if it refers to a flow of ideas rather than just one clever idea. I'm looking for a word that's ***commonly used***.

Answer 1

Suggestion may be cognition or re-focus.
