Fig. 4From: RFamidergic neurons in the olfactory centers of the terrestrial slug LimaxThe expression maps of 9 RFamide genes in the ST. Schemata showing the distribution of the neurons expressing RFamide genes in (a) horizontal and (b) coronal sections. c Examples of images of in situ hybridization in horizontal sections of the left ST. Positive signals are in red, and nuclei are in blue. White arrows indicate some of the positive signals. The cartoon on the right explains the direction of the sectioning plane. Scale bars: 200 μm (applicable to all photographs). D, dorsal; V, ventral; A, anterior; P, posterior; R, right; L, leftBack to article page
