No, really, they cannot. Even the brain itself is 
not aware of its own topology. It could not 
possibly be: that would need at least a much 
bigger brain. Even if one were given a complete 
(dead) mammalian brain, there is no conceivable 
way to reconstruct all the neural connections in 
it, since the total cross-section of a neuron's 
end branchings greatly exceeds that of its axon, 
and these neurons are tightly packed in the 
cortex. Any way to 'take it apart' to find all 
the neurons, therefore, would of necessity 
involve breaking the connections which hold them 
together. Put another way: its impossible to 
assemble (or disassemble) a brain; it has to be 
grown.    (02)

For more on this and many other fascinating 
neural topics, see books by Valentino Braitenberg.    (03)
