I'm looking for an elegant phrase describing why group brainstorms are effective.
At the moment I have "allows one person to spark ideas in another".
It doesn't seem right, what's a better verb or phrase?

stimulate VERB [WITH OBJECT]
1Raise levels of physiological or nervous activity in (the body or any biological system)

1.1 Encourage or arouse interest or enthusiasm in.
the reader could not fail to be stimulated by the ideas presented
1.2 Encourage development of or increased activity in (a state or process)

I think the reason why "sparking one's interest" works is because it stimulates the mind as applied to a topic as described above
