Often when I'm talking I'll start off with a single idea and it will slowly progress into something completely unrelated. Well perhaps not completely unrelated... normally what happens is that I'll be on a subject and a 'keyword' will come up in the conversation and suddenly I'll find myself going on about that.

Which is really interesting because keywords are a good way to explain how the brains memory functions. What happens is that your brain stores information all over the cortex that's connected by axons and dendrites in a complicated web of neurons. If you think of a keyword as a single point in the memory; what happens is that there are several branches that lead off into objects related.

IE> Think of apple. Apple itself is a single keyword, but there are a million little branches that break off into things you relate apple to. Adam & Eve, green, McIntosh, sauce, computers...

and these brances work together to make whole ideas and concepts through cognitive selection.
