    Is this a surprise? It makes sense that we'd think in analog, not in digital... The concepts still hold, it's just not in ones and zeros.

    Well...what models work on a large scale and what models work on a small scale can be a different issue. The firing of a neuron is pretty much a binary process that either does or does not happen. But that doesn't necessarily mean that everything that's built up on top of it appears highly binary in nature, like you said.

    But I think you're right, stridey... nothing in this article seemed terrifically surprising to me as a psych grad student.

    There's also the other sense in which we're fortunately learning that this basic statement is true: the brain is also not like a computer in the sense that it is not a general purpose computational device. It is designed to perform certain tasks exceedingly well, and all the developments that we've made culturally are built up on top of those basic (specific and not general) abilities....
