Stuart:
This is actually a very cool idea. I see how Josephson junctions do act a lot 
like biological neurons. But there are also other features of JJs that are 
"value added". One thing that springs to mind is that Josephson junctions are 
also used in super-conducting quantum interference devices (SQUIDS) because 
they are extraordinarily sensitive to minute magnetic fields. SQUIDS can even 
measure the tiny magnetic fields produced by biological brains. The 
implications of this ability are quite interesting. Artificial brains that 
could detect or perhaps even read the thoughts of other brains might be 
possible. Kind of like built- in ESP. I will have to think about it more, but I 
wanted to separate it from the noise of the other thread. Thanks Serafino.

But, at the end, he writes: "It has been speculated that in the brain, the 
quantum superposition, entanglement and collapse could play a role as these 
might improve the computing power of the brain. On the other hand, it has been 
argued that the brain cannot support the required quantum coherence. The 
principles of quasi-quantum computing might still be applicable to the brain as 
these do not call for any exotic physical conditions for their operation. The 
communication between neurons may rely, in one way or other, on kinds of 
superposition states that collapse to final states aided by learned 
entanglement rules. At the moment, this hypothesis remains to be verified by 
further research. It also remains to be seen if this quasi-quantum approach 
will have any value for practical applications and for the theory of computing, 
or if this approach will merely remain an intellectual curiosity."
It seems Haikonen has 'hella' informations about conscious machines, and there 
emotions .... http://personal.inet.fi/cool/pentti.haikonen/
[hella seems to be the new SI prefix meaning 10^27, like in hella-gram]
