Numbers for humans vary rather a lot. Some types of cells have up to
200,000 connections (Purkinje neurons) while others have very few.
Thus talking about the number of synapses per neuron doesn't make
much sense. It all depends on which type of neuron etc. you mean.
Anyway, when talking about

The man issue is, we we still have basically no idea of the patterns
according to which the neurons in the mouse brain are really interconnected,
except in some particular regions ... so semi-randomly hooking up 8 million
(well-simulated individually) neurons is not really simulating half a mouse
When I first saw this on the BBC web site I thought it looked exciting -
maybe the first upload. But on closer inspection it seems to be less
impressive. There is an extremely brief report on what they did, which
looks like merely simulating a large number of neurons on a supercomputer,
without
Does anyone know if the number of synapses per neuron (8000) for mouse
cortical cells also apply to humans? This is the first time I have seen an
estimate of this number. I believe the researchers based their mouse
simulation on anatomical studies.
