Figure 5-11.
Frontal section showing biocytin-labeled retinofugal fibers and their terminals in the optic tectum. Fibers are mainly seen in the stratum opticum (SO) and stratum fibrosum et griseum superficiale (SFGS). Labeled fibers are dense in the superficial portions of the SFGS, but less dense in the deeper portions. Considerably fewer fibers and terminals are found in the stratum album centrale (SAC). Scale bar, 25 μm. SGC, stratum griseum centrale; SM, stratum marginale; (Reproduced from Deguchi et al., 2005, with permission of The Zoological Society of Japan; Copyright (2005) The Zoological Society of Japan.)
