According to Kurzweil in "The Singularity is Near", a neuron-firing
cycle takes under 20 milliseconds to perform, which works out to 50Hz
Elsewhere he mentions something like a neuron performing 200
'operations' per second, which you might interpret as 200Hz.

In either case, its way less than 2000Hz.
