Nitpick: voltage potentials and ion channels. There's not much actual current flowing.

Nitpick over nitpick: synapses are not exactly electrical or ion current based, they have active transporters.

If all electrical activity ceases, does memory survive? (Answer is very likely yes given cryonic experiments. Brain is protein, ion currents have tendency to auto fire on defrost.)

Ah, I was under the mistaken assumption that ion transport was a subset of ion channels but I see now the latter is passive only.
