You're probably thinking of the _Aplysia_family, 
marine invertebrates with a small number of very large neurons which
were used notably by Eric Kandel in his pioneering research on synaptic
mechanisms.  His _Principles_of_Neural_Science_ is an excellent 
technical overview.

Gordon Shepherd's introductory neurobiology textbook, simply called
_Neurobiology_ is a good way to learn about the basic principles of
how nerves and synapses work, which is the foundation of what you are looking
for.   It covers from the molecular to the cerebral levels of organization,
stopping just short of describing neural nets.  

TO bridge that gap, you might consider something like 'Wet Mind,' which is
a general readership overview of cognitive neuroscience.

					hope this helps,
