Summary of the localization of 12 RFamide genes in the CG and ST/IT
| Abundance and distribution in the CG (Fig. 3) | Right-left symmetry (Fig. 3) | Characteristic expression pattern in the CG (Fig. 3) | Abundance and distribution in the ST/IT (Figs. 4 & 5) | |
|---|---|---|---|---|
| FMRFamide | Many in the dorsal aspect of the CG. No positives in the PC | Asymmetrical (A cluster of neurons in the ventro-posterior region of the right CG) | A pair of large neurons (probably C3 motor neurons, [9]) in the dorso-anterior aspect of the PC | Scattered in the marginal area, away from the digit |
| LFRFamide1 | Many in the CG (including the PC) | Symmetrical | A pair of large neurons at the basal region of the PC | Expressed in a majority of neurons in the cell mass at the basal region |
| LFRFamide2 | Many in the CG (especially abundant the PC cell mass layer) | Symmetrical | A pair of large neurons at the basal region of the PC | Many along the borderline between the digits and neuropiles |
| CCK/SK1 | Many in the basal region of the PC | Symmetrical | Found in the apical region | |
| CCK/SK2 | Most of the positives were localized to the CG other than the PC | Asymmetrical (Two neurons in the dorsal aspect of the left CG) | A pair of positives at the basal region of the PC | No positives in the ST/IT |
| NP-F1 | Most of the positives were localized to the CG other than the PC | Asymmetrical (One large and one small positives located in the dorsal aspect of the respective right and left CG) | A pair of positives at the basal region of the PC | Localized primarily in the cell mass in and near the digits |
| NP-F2 | Expression in seemingly all the PC neurons, and in several neurons in the other CG regions | Symmetrical | Conspicuous signals aligned in two rows in the PC | Localized to near the apical region |
| pedal peptide | Many positives in the PC, and a smaller number in the other CG regions | Symmetrical | Many positives along the edge of the cell mass and terminal mass layers of the PC | Localized to the digits cell mass, with some positives found in the putative photoreceptors of an eye |
| FaRP-A | A small number in the CG, but none in the PC | Asymmetrical (a culster located in the dorsal aspect of the right CG) | A small number of positives | No positives in the ST/IT |
| FaRP-B | Only 3 pairs of positives in the CG, including one pair in the basal region of the PC | Symmetrical | All 6 positives reside in the dorsal aspect | No positives in the ST/IT |
| luqin1 | Positive neurons in the mesocerebrum, dorsal aspect of the metacerebrum, and in the basal region of the PC | Asymmetrical (larger number in the right mesocerebrum) | Many large positives in the mesocerebrum. | Scattered in the cell mass at the basal region, and also in the apical region |
| luqin2 | A cluster of 5–9 positives in the dorsal aspect of the matacerebrum, and a cluster of 5–7 positives in the basal region of the PC | Symmetrical | No positives in the ventral aspect | A few positives in the anterior to an eye in the ST, whereas no positives in the IT |
