I also find it interesting. Specially in history. In his book: "The Root of Thought" (http://www.scientificamerican.com/article/the-root-of-thought-what/ http://www.scientificamerican.com/article/the-root-of-though...) Dr. Andrew Koob, talks about the importance of Glial cells and the possibility of it being responsible for consciousness. I think with the new technological innovations in the field of Neuroscience we might get a better understanding of what these cells actually do in the human brain, other than "glue" things together.
