I don't think his 5-500Hz numbers are even remotely correct.

Just because that is the aggregate signal detectable outside the brain doesn't mean the individual neurons are anywhere near that slow.

In fact considering I can easily react to something in under 1/5 of a second, it's provably wrong.

And I can react even faster to expected stimulus, for example to keep my balance, or play a piano. 500Hz simply makes no sense.



A typical spike is of the order of 2msec, so required time step should be of that order. In detailed neuronal simulations, one usually uses a time step of 0.1msec
