Here are some references, with brief notes. They are not in any 
particular order. My experience is limited to methods that use
the Golgi-Cox mixture as the primary fixative. Kolb & McLimans
(1986) is a good modern method of this type. If you have a vibrating
microtome (vibratome) you should get nice 100um sections for
looking at dendrites.

 FISH, P. A. 1895
 The use of formalin in neurology.
 Transactions of the American Microscopical Society 17, 319-330.

 Review (31 refs) followed by some original observations. Recommends Water
 2000, Formalin 50, NaCl 100, ZnCl2 15. Fix brain 7-10 days. Perfuse 
 vessels & inject cavities if possible. Post fixation in 2.5% formalin, 
 or various mercury, picric, dichromate solutions. Also various 
 Golgi-type methods; formalin- dichromate mixtures must be kept in 
 darkness.

I hope these will help you to choose a suitable technique.
