The 1GHz clock speed for microprocessors is straightforward.
The 100Hz for the brain is a bit complicated. If we’re just talking about how frequently a neuron can fire, then sure, 100Hz is about right I think. Or if we’re talking about, like, what would be a plausible time-discretization of a hypothetical brain simulation, then it’s more complicated. There are certainly some situations like sound localization where neuron firing timestamps are meaningful down to the several-microsecond level, I think. But leaving those aside, by and large, I would guess that knowing when each neuron fired to 10ms (100Hz) accuracy is probably adequate, plus or minus an order of magnitude, I think, maybe? ¯\_(ツ)_/¯
Does anyone have a citation for this claim?
I think we’re dividing 1GHz by 100Hz.
