Dark Matter of the Brain, Continued

  1. Carl,

    Slightly unrelated, but in the September Discover column, you say: “Even though the brain contains about a trillion glia—10 times as many as there are neurons”.

    In the spirit of fact-checking, what do you think of this article, questioning the veracity of that figure? http://www.springerlink.com/content/w10q224721mmw8u6/fulltext.html; see also this blog post,

    I’ve been mean to dig into this in my oh-so-abundant free time but perhaps you have done so already.

  2. Whoops, sorry for the un-proofread comment, above. I would edit it if I could. (The omitted link was to a blog post of little value.)


    Don’t you mean ‘gray matter’?
