Fig. 1. Olfactoretinal centrifugal pathway in zebrafish. (A) Schematic
representation of the location and projections of the terminal nerve (TN). Red
circles and red lines label TN cell bodies and their axons, respectively. The
broken line drawn between OB and TE indicates the location of the olfactory
bulb lesion. OB, olfactory bulb; TE, telencephalon; TC, tectum opticum; RE,
retina. (B) A confocal image of a whole-mount preparation of the olfactory
bulb showing TN cell bodies and their axons (labeled with an antibody against
FMRFamide). Anterior is to the left. Scale bar, approximately 35 µm for
B.
