For Nikon RAW files (.NEF), the file contains both the original camera data, 
plus the instructions for "developing" it--i.e. tone curve, sharpening, 
color space or B&W, etc., etc.  The Nikon Capture editor will edit the 
developing instructions without changing the original camera data.

So yes if you have a B&W .NEF file, the original camera data is there, and 
you have all the same tonal range as a color .NEF file, which you manipulate 
with the same controls (except there is only one channel, not R, G and B).

It is a mistake to believe that a RAW file only contains the raw data from 
the camera's sensor.  It generally contains all the other shooting settings 
that were current when the camera took the picture.
