Longitudinal section of the kidney showing IR-staining (thin arrows) possibly as innervations to smooth muscles within the kidney tissue and also in the periphery, kl. kidney lumen; me, mantle cavity. Scale bar: 300 ^ The distribution of IR-neurons in the CNS is mapped in Figure 7. All commissures, connectives, and major nerves in the CNS display IR-fibers, and all ganglia except the pleu- rals contain IR-cell bodies. Visceral and right parietal gan- glia contain both large (20 ± 5 /am) and small ( 10 ± 5 jam) IR-neurons, whereas mostly small and only a few large IR-neurons are found in the cerebral and pedal ganglia (Figs. 7-9, 12). Cerebral ganglia. Two groups of large (20 ± 5 jam) and small (10 ± 5 /am) IR-neurons are present at the anterior and posterior location of the cerebral commissure (Figs. 7-9). The middle part of each cerebral ganglion contains
