>Well, one major difference is that the rat brain is much smaller than
(most) human brains.
More seriously, it would be very hard to generalize your question, as
there are many regiospecific differences. For example, the rat has a
much more developed olfactory system than humans, while the visual
cortex is probably less developed. The basic structures are similar in
form between species, but there relative sizes & locations will vary
from species to species. To answer your question, you'd probably need
to find information on the specific area you are interested in.
