The presence of UCN3-ir neurons and fibers, as well as UCN3 mRNA, are indicated by a plus sign, and their absence is indicated by a minus sign. The relative density of UCN3-ir fibers in different brain regions agrees to the patterns shown in Figure 1, indicated by the number of plus signs depending on the amount present in a specific region or with a minus sign to indicate the absence of labeled fibers.
