The most reasonable estimates give about 50 billion (5x10^10) neurons
in all, of which about 40 billion are granule cells in the cerebellum.
About 10 billion are in the neocortex; all other numbers are much
smaller. The number of synapses would be around 100 trillion (10^14),
of which more than 90% are in the neocortex.
