This is a really cool post and I love seeing posts about human neurons on Hacker news. Especially this one talking about the different glial cells, as most people only think about the brain in terms of neuronal connections between synapses and think none of the housekeeping.

I tried to find the other segments for this series and could only find the first four chapters, so I'm wondering if there are more. But for anyone really interested in neuroscience on a biological level, "Principles of Neural Science" by Kandel and Schwartz (also one of this article's references) is your bible.
