That's probably off by a couple of orders of magnitude or so. I had some rough estimates a while back, the numbers were between single digit to tens of Billions, depending on neuron activity.
The calculation is fairly trivial, you simply compare the sum of neurons operating simultaneously and their switching rate versus transistors and their switching rate. Then you have a relative comparison of raw computation, of course not taking into account the efficiency, in terms of how it is used. However I don't recall the typical sum of active neurons and their average switching rate, but I do recall the number was in the Billions and it was a good estimate that was generally agreed upon.
