“…Recent neuroanatomical studies in Takifugu niphobles demonstrate that the processes of the clustered supramedullary cells project peripherally through the trigeminal, vagal and spinal nerves (Funakoshi et al, 1995). Our previous immunohistochemical research on the detection of neuropeptides show that aligned supramedullary neurons exhibit positive immunoreactivity to , both in Perciformes (Coris julis) (Benedetti and Mola, 1988) and in Scorpaeniformes (Trigla lucerna and Scorpaena porcus) (Benedetti et al, 1993). Funakoshi et al (1998) confirm gastrin/CCKimmunoreactivity in T. niphobles clustered supramedullary neurons.…”

“…It is improbable that species differences can account for the diversity in immunoreactivities to TH between C. julis and T. niphobles. Indeed, in all species that have been studied by different authors, the supramedullary cells, both aligned and clustered, share the same main morphological (Marini and Benedetti, 1992;Cuoghi and Marini, 2001) and immunohistochemical (Benedetti and Mola, 1988;Benedetti et al, 1993;Funakoshi et al, 1998) characteristics. Moreover, immunopositivity to anti-NA was also found in the clustered supramedullary neurons of the pufferfish Tetraodon fluviatilis (Cuoghi, unpublished data).…”

SUMMARYThis study, carried out on Coris julis (Labridae), is a contribution to the immunocytochemical characterization of fish supramedullary neurons. The significance of these giant cells has been debated since the beginning of the twentieth century. Our research provides the first evidence for a noradrenergic feature of this neuronal system. The possible role of supramedullary neurons as components of the autonomic nervous system is discussed. Moreover, the present results, taken together with our previous studies, surmise that this the first known case of colocalization of a neuropeptide (gastrin/CCK-like) and noradrenaline in the nervous system of teleosts.

The supramedullary cells (SMCs) of teleosts have been studied for nearly 100 years, but their peripheral connections have remained obscure. We examined the supramedullary cells of the puffer fish, Takifugu niphobles, using horseradish peroxidase transport. Horseradish peroxidase labeling was found bilaterally after application to the trigeminal, the posterior branch of the vagal, and the spinal nerves. No labeled neurons were found after application to the anterior or visceral branches of the vagal nerve. Thus, labeled SMCs were found only after application to the nerves containing cutaneous branches. Some rostrocaudal topographical labeling was found after selective application to each of the four branches of the trigeminal nerve. Labeled neurons were more common in the rostral than in the central or caudal part of the SMC region. Some topographical labeling was also found after application to the first, second, and third spinal nerves, but the topography was not very clear, and there was considerable overlap in the distribution of labeled cells. The sum total of labeled SMCs after unilateral horseradish peroxidase application to each peripheral nerve was more than three times the total number of ipsilateral SMCs, indicating that a single SMC projects several peripheral processes into different nerves. From these results, and taking previous studies into consideration, we propose that supramedullary neurons have a phylogenetic relationship with the spinal dorsal cells of the lamprey and with the extramedullary cells of the amphibian embryo.
