Indeed! It is the soup (as I have been saying) that also contributes
to "information processing"; not only the extracellular soup, but the
soup/structures/functions within each neuron as well; much of which,
it is presumed, has chaotic aspects, albeit with some emergent goals
that seem to lend themselves to autopoiesis.
