"This thing you think of as you: it spreads across two cerebral hemispheres connected by the corpus callosum, a fat meaty pipe more than 200 million axons thick." From the article. It's interesting because, compared to the massive parallelism in each hemisphere, the connection between the two doesn't seem all that large. Individual neurons also seem to have to have a fairly slow response time, on the order of milliseconds from what I've read. IANANeuroscientist, but that could be a manageable amount of data?
