There is a much more recent thionin-based technique for differential
staining of nerve cells and fibres. The protocol developed by Tolvia,
Navarro, and Tovia (1994) in Histochemistry, 102, 101-104 is described for
paraffin-embedded CNS tissue, but I have found it works equally well for
cryostat sections. It is fast, easy, and produces beautiful looking
sections.
