If the above calculation of 4E15 is correct, then the average brain cell would need to fire 4E4 times per second.

We have about a billion transistors (processor gurus, is this number approximately up to date?) so about a quarter of a billion gates, operating at about 4 billion Hz. If they all switched every cycle that would be about 1E18 “firings” (ignore for the moment the term may or may not be applicable.) If I go into task manager, I see that about 1% of the CPU is busy as a rough estimate. So perhaps 1E16, or I would be OK with your 4E15, give back another factor of 2.<u></u><u></u></span></p>
