The thing that surprises me is: how does it get distributed widely enough? I would imagine that 30pg would lump together somewhere and damage a handful of neurons, not that it would spread and reach all essential parts of the nerve system.

The wikipedia article claims, without citation: "The extracellular fluid is constantly "stirred" by the circulatory system, which ensures that the watery environment which bathes the body's cells is virtually identical throughout the body. This means that nutrients can be secreted into the ECF in one place (e.g. the gut, liver, or fat cells) and will, within about a minute, be evenly distributed throughout the body."
