Ten steps might not be ridiculous if you can do a
Fourier transform in two steps, or do principle
component analysis in two steps. Which apparently you
can. See Neural Engineering, below. Remember the
ten-step rule is only for fast reactions, of the type
that insects manage with only thousands of neurons.

Some books you might look into, all from the MIT

On neural coding, specifically wrt spikes:
Spikes: Exploring the neural code, by Rieke and
Warland 1997.
Pulsed Neural Networks, by Maass and Bishop, 1999.

On computing with neurons: A really REALLY
outstanding book called Neural Engineering, by
Eliasmith and Anderson, 2003.
