In a recent post entitled Week 3: Rhizomatic or biological neuralogical network?, my colleague in CCK12 Matt Bury writes that he's "been pondering the analogy of distributed networks of learners, i.e. Connectivism, as rhizomes" and concludes that he "wasn’t convinced by it from the start." You can read the rest of Matt's thoughtful comments on his blog, but if I understand him correctly, he doesn't see a tight fit between botanical rhizomes and networks of people. Actually, he seems to prefer neurological networks, which appear to be structured much more like social learning networks. I, too, have found neural networks to be most helpful in understanding networks in general and neural networks in particular, and I heartily refer interested scholars to Olaf Sporns' book Networks of the Brain.
