“…These findings may possibly account for the persistence of vestiges of the original trigeminal oscillator and for the high homology between the pTRG and the preBötC. It should be kept in mind that within the brainstem and spinal cord neural circuits capable of generating rhythmic motor behaviors develop in a segmental fashion (see Kinkead, 2009;Taylor et al, 2010). Each major group of respiratory motoneurons has been suggested to be coupled to its own rhythm generator (Champagnat and Fortin, 1997).…”

“…In fact, the evolutionary origin of respiratory mechanisms in vertebrates is from structures and pumps initially associated with feeding (Rovainen, 1996;Kardong, 2006;Kinkead, 2009;Milsom, 2010;Taylor et al, 2010). At this stage, the trigeminal motor mechanism plays a prominent role and is the first mover in the respiratory sequence that also involves other cranial motor nuclei.…”

“…It is mainly responsible for velar pumping in the larval lamprey and for buccal pumping in jawed fishes (see e.g. Taylor et al, 2010). In addition, the velum of larval lampreys in the adult becomes a valve that allows breathing when the mouth is engaged in feeding behavior (Kinkead, 2009).…”

“…From an evolutionary point of view, we should recall that in air-breathing fishes, amphibians, reptiles, birds and mammals the respiratory activity changes progressively from a buccal/branchial ventilation to a ventilation primarily driven by an aspiration pump (Kinkead, 2009;Milsom, 2010;Taylor et al, 2010). Despite the differences displayed by the different species in the pattern of conveying air and in the function of the respiratory muscles, evidence is accumulating that the respiratory rhythm generator within the reticular formation has shifted from a position close to the trigeminal nucleus, that has lost its primary pumping respiratory function, to a location close to the other cranial motor nuclei.…”

“…These latter, along with spinal motor nuclei innervating the intercostal muscles and diaphragm, progressively acquire a prominent respiratory role. These changes in the location of the respiratory CPG obviously imply a caudal migration of the original rhythm generating mechanism or the development of a new respiratory oscillator or multiple oscillators, entrained to a large degree (Wilson et al, 2002(Wilson et al, , 2006Vasilakos et al, 2005;Taylor et al, 2010;Kottick et al, 2013). The respiratory CPG of higher vertebrates and mammals remains placed in a cranial strategic position to drive close brainstem motoneurons that have to be engaged in advance and to send excitatory projections to lower respiratory muscles innervated by spinal motoneurons.…”

a b s t r a c tThe isolated brainstem of the adult lamprey spontaneously generates respiratory activity. The paratrigeminal respiratory group (pTRG), the proposed respiratory central pattern generator, has been anatomically and functionally characterized. It is sensitive to opioids, neurokinins and acetylcholine. Excitatory amino acids, but not GABA and glycine, play a crucial role in the respiratory rhythmogenesis. These results are corroborated by immunohistochemical data. While only GABA exerts an important modulatory control on the pTRG, both GABA and glycine markedly influence the respiratory frequency via neurons projecting from the vagal motoneuron region to the pTRG. Noticeably, the removal of GABAergic transmission within the pTRG causes the resumption of rhythmic activity during apnea induced by blockade of glutamatergic transmission. The same result is obtained by microinjections of substance P or nicotine into the pTRG during apnea. The results prompted us to present some considerations on the phylogenesis of respiratory pattern generation. They may also encourage comparative studies on the basic mechanisms underlying respiratory rhythmogenesis of vertebrates.

1. Freshwater mussels (Unionoida) are globally threatened. The key to the development of effective conservation strategies for this group is to unravel their complicated life cycle, including the obligatory larva, which parasitizes the external tissues of fish.2. Artificial infestation was conducted for three fish species -Barbus barbus, Chondrostoma nasus, and Squalius cephalusin order to study the prevalence, site, and intensity of infestation, in relation to the fish species and their individual body size. Fish gut contents were also examined, in order to analyse the possibility of glochidia consumption.3. Glochidia of Unio crassus are considered parasites of fish gills; however, this study revealed that U. crassus glochidia were attached to the fins of all the host species tested. The number of glochidia attached to C. nasus fins was four times higher than the number of glochidia attached to gills. 4. The prevalence of fin infestation was higher for C. nasus and S. cephalus than for B. barbus.Infestation intensity was highest for C. nasus and lowest for B. barbus, and was also dependent on fin type. The number of glochidia attached to fins demonstrated a nonlinear (log 10 ) relationship with fish body length. 5. Inspection of dissected fish guts showed that all of the fish species tested foraged on glochidia:S. cephalus and B. barbus more frequently than C. nasus.6. Using predatory fish host species with non-predatory species in mixed assemblages for artificial rearing of mussels led to increased mortality of fish and decreased infestation intensity. 7. The best conservation practices for freshwater mussels should therefore be based on single fish species that are easy to infest and that do not prey on glochidia.
