There are many things that are not yet known in neurobiology and 
in the higher organizational patterns of the brains, both in 
their computational structure and the dynamic interactions 
between their parts.

But we are not totally ignorant. Neurobiology and other brain 
sciences have discovered many things. This old guy  
http://en.wikipedia.org/wiki/Gerald_Edelman  has proposed several 
theories (http://en.wikipedia.org/wiki/Neural_Darwinism ), done 
simulations; and generally all kind of researchers are increasing 
our knowledge of such topics every day, so currently we are not 
in the full dark as you say.

The differences in the brains of different animals are slowly 
getting understood, including what's the difference between the 
consciousness of dogs, self-consciousness of humans, simpler 
brains of reptiles, and cabled aggregates of bodies inside tiny 
insect brains (as it often happens in biological sciences, what 
we discover is that even the 'simplest brains' are quite more 
complex than previously believed. Today we know how a fruit flies 
learns and remembers scents, how its tiny brain copes with the 
needs of a complex body able to fly in a very complex 
environment, etc).
