Actual Size 10 X 6 mm.] A collection of gray matter forming one of the most conspicuous ele- ments in the dorsal fields at this level is the extensive substantia gelatinosa trigemini (NR) which acts as a relay station for all fibers bearing im- pressions from the trigeminal areas of the face and head. This area of innervation corresponds to the region anterior to the interparietal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Tilney, Frederick, 1875-1938; Riley, Henry Alsop, 1887-.
