"On its own this trigger, as we can see from the earlier definition, is not going to generate consciousness. Imagine a candyfloss machine with a stick in the centre that then gathers more and more candyfloss as time goes on. Think of the epicentre as the stick in the centre, the burgeoning candyfloss being analogous to the recruitment of the cells. The stick in itself is not the candyfloss, it is just the trigger for it, just as the stone does not contain the ripples but causes their generation."
— Greenfield, Susan (b. 1950)
