Glomerular organization of the malleolar neuropil, detail. a Transversal section through the anterior and ventralmost neuropil of the synganglion in Galeodes turkestanus (paraffin histology). Glomerular structures are clearly discernible in the compact malleolar neuropil, surrounded ventrally and laterally by somata, and dorsally and more laterally by neuropil of the pedipalpal neuromere. Ventrally, this histological section is delimited by the ganglion surface. b Schematic representation of individual glomeruli of the malleolar neuropil, frontal view. Glomeruli are shown as maximum projections along the longitudinal body axis, and thus partly appear to overlap due to their skewed arrangement (compare Figs. 3c and 4). More anterior and more posterior glomeruli are indicated in darker and lighter shadings, respectively. An exploded view of the glomerulus arrangement surrounds the neuropil reconstruction. Positions of the individual glomeruli are indicated by lines emerging from the frontal view. Numbering corresponds to Fig. 5b. The reconstructed glomeruli are tilted by about 45°, posterior end up, to illustrate their shapes and approximate sizes. Histological section planes (10 μm) are indicated by contour lines. For all images, dorsal is to the top and lateral to the right
