“…The reticular formation provides a major input to the nucleus ambiguus of mammals [47,48], and sparse input to the syringeal motor nucleus in parrots (not indicated in fig-IQ [49]. Other data indicate that reticular inputs to spinal or cranial motor nuclei are typical of verte brate motor nuclei [47,50,51], and do not represent a special feature of communication circuits.…”

Among vertebrates, there are a number of different neuromuscular systems specialized for the production of acoustic and electric social communication signals. Each system involves distinct sets of striated muscles that are derived from paraxial mesodermal somites and are components of a peripheral effector or 'communication organ': the larynx and syrinx of tetrapods, the sonic swim bladder and electric organ of fishes. Each of these systems further exhibits species-typical characters ranging from the number of muscles involved to myofibrillar architecture. Given that communication uses striated muscle, its circuitry is seen to represent a modification of existing motor systems. Thus, it is not surprising that these systems share several features suggesting that common mechanical or developmental factors influence their evolution. Of prime importance in comparing central communication circuitry between fishes and tetrapods is that among tetrapods the sound-generating organs are a part of the ventilatory system and so their activity must be coordinated with other sets of neuromuscular units. Differences in the central pattern of circuitry are thus expected between fishes and tetrapods, as well as among tetrapods themselves, since ventilation mechanisms differ between taxa. Moreover, birds have independently evolved a vocal syrinx which is distinctly separate from their larynx.

“…In mammals these effects are mediated by inhibition and/or excitation of both the vagal complex in the medulla and sympathetic cardiac nerves. The path ways by which hypothalamic cardiac responses are mediated in teleosts are unknown, though hypothalmomedullary connections have been described [Ariens-Kappers et al, 1936;Schnitzlein, 1964;Luiten and Pers, 1977;Morita et ah, 1983] and these could potentially control HR via connections to brainstem nuclei.…”

Neural control of heart rate (HR) was investigated in goldfish, Carassius auratus, using electrical stimulation of the brain. Three types of HR response were evoked by stimulation: HR decreases during stimulation (type I); HR increases during stimulation (type II), and HR decreases during stimulation, followed by increased rates at the offset (type III). Type I bradycardias were evoked by stimulation of the preoptic area and diencephalon, specifically in the ventral thalamus-dorsal hypothalamus transitional area, and the region dorsal and medial to the nucleus glomerulosus. Additional sites were located above crossing tectobulbar fibers in the midbrain and in basolateral medullary reticular areas, motor nucleus of the vagus and caudalmost vagal roots. Type II tachycardias were evoked by stimulation of sites in the dorsal telencephalon, inferior lobes of the hypothalamus and dorsomedial region of the vagal lobes. Type III rebound tachycardias were evoked from sites dorsal and medial to the nucleus glomerulosus and in the inferior lobe of the hypothalamus. The location of cardioactive sites in the brain in goldfish is comparable to that in other vertebrates; however, these cardiac responses may be mediated by faciliatory or inhibitory pathways to the vagal motor nuclei rather than sympathetic cardiac nerves.

ROBERTS, J. L., and ROWELL, D. M. 1988. Periodic respiration of gill-breathing fishes. Rhythmic and arrhythmic patterns of breathing are common among gill-breathing fishes. Irregular, short bouts of apnea occur in most fishes during feeding, while long apneic periods are routine for many open-water fishes such as scombrids, which ram ventilate during cruise swimming. During ram ventilation, the work of gill ventilation is transferred from the respiratory to the swimming musculature, with energy savings due to reductions in drag and inertial losses. Noncontinuous swimmers, such as some benthic and midwater marine and freshwater species, seldom cease rhythmic respiratory movements or resort to ram ventilation. When quiescent, they may adopt patterns of secondary cycling, alternating between respiratory pauses and short periods of rhythmic branchial pumping. Types and locations of chemo-and mechano-receptors that trigger changes in respiratory patterns of fish are being identified, as are the reflex pathways linking them to brainstem respiratory centers. A new mechanoreceptor is described that overlies the adductor mandibulae jaw muscles and may be of use in the modulation of cyclic respiratory movements. Respiratory switching control between rhythmic and ram gill ventilation is discussed. ROBERTS, J. L., et ROWELL, D. M. 1988. Periodic respiration of gill-breathing fishes. Can. J. Zool. 66 : 182 -190.L'existence d'un double mode de respiration, rythmique et arythmique, est un phknomkne commun chez les poissons h respiration branchiale. Des pCriodes irrkgulikres et courtes d'apnCe se produisent chez la plupart des poissons durant l'alimentation, alors que des pkriodes d'apnCe longues sont monnaie courante chez les poissons qui vivent en milieu ouvert, tels les Scombridae qui utilisent la ventilation par compression lorsqu'ils nagent sur de grandes distances. Durant la ventilation par compression, I'activitC de ventilation des branchies est transfkrke de la musculature respiratoire h la musculature natatoire, entrainant une Cpargne d'Cnergie par diminution de la trainCe et des pertes par inertie. Les poissons ii nage non continue, comme par exemple certaines espkces benthiques ou les poissons marins ou dulcicoles vivant h des profondeurs moyennes, cessent rarement leurs mouvements respiratoires rythmiques et utilisent rarement la ventilation par compression. En repos, ces poissons peuvent utiliser des patterns secondaires avec alternance de pauses respiratoires et de courtes pCriodes de ventilation branchiale rythmique. Des Ctudes courantes permettent de reconnaitre et de localiser les types de chimioricepteurs et de mCcanorCcepteurs qui dCclenchent les changements respiratoires chez les poissons; les voies rkflexes qui relient ces changements aux centres respiratoires situCs dans le pCdoncule cCrCbral sont Cgalement en cours d'Ctude. On trouvera ici la description d'un nouveau mCcanorCcepteur qui surplombe les muscles adducteurs de la mandibule et joue probablement un rdle dans la modulation des mouvements du cycl...
