"Well, it’s more like dreaming about neurology. You had me all excited, and I was right on the edge ... you know how you can sort of hang there where it’s wonderful, right on the edge? And I was thinking hard about wave propagation in glial cells. Then suddenly it came to me, that the standard calcium-wave astrocyte story is all wrong, there’s a better method to describe that depolarization, and I almost had that idea, I almost had it, I almost had it, and I just got stuck there. I got stuck there on the edge. I couldn’t get loose and I couldn’t quite come and the pleasure kept building up. My head started roaring, I was almost blacking out. And then it came all over me, in a tremendous rush. So I had to jump out of bed to write it down."
