Hello, I don't know much about molluscan but I do know histology. There are many stains for nerve fibers, astrocytes, myelin and nerve cells. I would first do H&E staining to assess the regions of interest. Then depending on what your looking for, do special stains. If you email me directly [email protected] with specifics about what parts of the nervous system you want, I will send you the staining protocols and tips to getting your project done. Our website http://histologistics.com/ has an abundance of pictures, protocols and other information about staining for all types of tissues. Let me know.

Thank you
