I really wonder how one could establish the required parallel connection. You need quite the wide connection interface ... (If I recall correctly brains work in a parallel fashion.)
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?
