Human brains are not computers. There is no "memory" separate from the "processor". Your hippocampus is not the tape for a Turing machine. Everything about biology is complex, messy and analogue. The complexity is fractal: every neuron in your brain is different from every other one, there's further variation within individual neurons, and likely differential expression at the protein level.
