Brainstorming
 

How do you say "brainstorming"? My dutch-Spanish dictionary gives "devanarse los sesos" but I can't find this in the Diccionario Real Academia Española?

devanarse los sesos = rack one's brain(s)
brainstorming = torbellino de ideas / tormenta de ideas

Thank you, but how do you use it as a verb then? Or don't they use it in Spain? Like, for example, "I have to brainstorm about this." How would you say that in Spain?

hacer una lluvia/tormenta de ideas

Tengo que hacer ...
Necesito hacer ...
