Summary The traditional view of the cnidarian nervous system is of a diffuse nerve net that functions as both a conducting and an integrating system; this is considered an indicator of a primitive condition. Yet, in medusoid members, varying degrees of nerve net compression and neuronal condensation into ganglion-like structures represent more centralized integrating centers. In some jellyfish, this relegates nerve nets to motor distribution systems. The neuronal condensation follows a precept… 

Cnidarian Nerve Nets and Neuromuscular Efficiency.

A comparison of neural control of two-dimensional muscle sheets in a mollusc and jellyfish suggests that a possible primitive feature of cnidarian neurons may be a lack of regional specialization into conducting and transmitting regions.

Origin and Evolution of the Nervous System Considered from the Diffuse Nervous System of Cnidarians

Cnidarians are considered the earliest metazoans to have evolved a nervous system and therefore offer possible insight into some of the fundamental properties of early nervous system, and are suggested to have primitive central nervous system.

Organization of the Ectodermal Nervous Structures in Medusae: Cubomedusae

The results offer insight into how the peripheral nerve nets of box jellyfish are organized to produce the complex swimming, feeding, and defensive behaviors observed in cubomedusae.

Atlas of the Neuromuscular System in the Trachymedusa Aglantha digitale: Insights from the advanced hydrozoan

The data uncovered the complex organization of neural networks forming a functional ‘annulus-type’ central nervous system with three subsets of giant axons, dozen subtypes of neurons, muscles and a variety of receptors fully integrated with epithelial conductive pathways supporting swimming, escape and feeding behaviors.

Back Through Time: How Cnidarians and Basal Metazoans Shed Light on Ancient Nervous Systems

The nervous systems of cnidarian neurons are electrically excitable, communicating with other neurons or muscles via chemical synapses, and forming diffuse neural networks with significant condensations along the main body axis.

A two‐step process in the emergence of neurogenesis

Striking examples are the ParaHox Gsx, Pax, Six, COUP‐TF and Twist‐type regulators, which seemingly exert neurogenic functions in cnidarians, including eye differentiation, and support the view of a two‐step process in the emergence of neurogenesis.

Neurons are defined as polarized secretory cells specializing in directional propagation of electrical signals leading to the release of extracellular messengers – features that enable them to

From nerve net to nerve ring, nerve cord and brain — evolution of the nervous system

It is proposed that expansion, integration and fusion of these centres gave rise to the bilaterian nerve cord and brain.

Functional modules within a distributed neural network control feeding in a model medusa

This work describes a coordinated, asymmetric behavior in which food is passed from the umbrellar margin to the central mouth via directed margin folding, and reveals how an organismal behavior can emerge from local interactions between functional modules in the absence of a central brain.

Evolution of sodium channels and the new view of early nervous system evolution

This addendum will attempt to put the finding of voltage-gated sodium channel genes, which make action potentials in nerves and muscles, in the LCA of animals and choanoflagellates, the closest unicellular relatives to animals, within the context of the new views of nervous system evolution.



Central Neural Circuitry in the Jellyfish Aglantha

Twelve neuronal and two excitable epithelial conduction systems are described and their interactions summarized in Aglantha, which lacks a brain, but the two marginal nerve rings function together as a central nervous system.

The bilaterally symmetric rhopalial nervous system of box jellyfish

The strikingly complex and partially bilaterally symmetrical nervous system found in each rhopalium of the box jellyfish, Tripedalia cystophora, is described and an atlas-like series of drawings are presented, indicating that visual processing and integration at least partly happen within the rhopalia.

The ring nerve of the box jellyfish Tripedalia cystophora

The morphology of the ring nerve of the box jellyfish Tripedalia cystophora is described as ascertained by normal histological techniques, immunohistochemistry and transmission electron microscopy, and the number of cells in theRing nerve is estimated by counting their nuclei.

Bilaterally symmetrical rhopalial nervous system of the box jellyfish Tripedalia cystophora

The strikingly complex and partially bilaterally symmetrical nervous system found in each rhopalium of the box jellyfish, Tripedalia cystophora, is described and an atlas‐like series of drawings are presented, indicating that visual processing and integration at least partly happen within the rhopalia.

Rhopalia are integrated parts of the central nervous system in box jellyfish

Results indicate that cubomedusae have one coherent CNS including the rhopalia, and a novel gastrodermal nerve has been found in the stalk; this nerve is not involved in visual processing but is likely to be mechanosensory and part of a proprioceptory system.

Neurobiology of Polyorchis. II. Structure of effector systems.

The gross and fine morphology of the major effector systems in the anthomedusan, Polyorchis penicillatus, is described and discussed in relation to the known physiological and behavioral properties

The anatomy of the nervous system of the hydrozoan jellyfish, Polyorchis penicillatus, as revealed by a monoclonal antibody

Immunohistochemical labelling with mAb 5C6 of whole-mount preparations and paraffin sections provided a far more complete picture of the organisation of the hydromedusan nervous system than was previously available when using neuronal labelling techniques that restrict labelling to certain neuronal types.

Both physiological and critical histological studies show that the coelenterate nerve-net is synaptic, and there is evidence that several distinct kinds of spontaneous activity are built into the normal behaviour mechanisms.

Neuronal control of locomotion in hydrozoan medusae

The swimming control systems of 13 hydromedusan species were examined electrophysiologically and morphologically to suggest that the basic organization of swimming system components is similar and may perform a pacemaker function.

Ultrastructure of synapses in the first-evolved nervous systems

The lack of postjunctional folds at neuromuscular synapses and the presence of fewer and somewhat larger synaptic vesicles in the more primitive animals suggests that neuropeptides evolved as neurotransmitters early in the animal kingdom.
