Abstract In order to solve the question whether Plathelminthes belonging to the taxon Acoela have a brain and an orthogon of the common flatworm type, an immunocytochemical study of the pattern of serotonin (5-HT) in four species was performed. In all species the 5-HT immunoreactivity revealed no ganglionic cell mass typical for other Plathelminthes, only a symmetrical brain-like structure composed of commissural fibres associated with a few cell bodies. 5-HT immunoreactivity was detected in… Expand

Figures from this paper

Organisation of the nervous system in the Acoela: an immunocytochemical study.
TLDR
The results support the view that the Acoela is not a member of the Platyhelminthes, and the pattern of 5-HT immunoreactivity revealed an anterior structure composed mainly of commissures, a so-called commissural brain. Expand
An endocrine brain? The pattern of FMRF-amide immunoreactivity in Acoela (Plathelminthes).
TLDR
The results indicate that the brain-like structure of A coela is not homologous with the brains of other Plathelminthes and implies an independent evolution of Acoela. Expand
The brain of the Nemertodermatida (Platyhelminthes) as revealed by anti-5HT and anti-FMRFamide immunostainings.
TLDR
It is demonstrated that the Nemertodermatida have neither a 'commissural brain' structure similar to that of the Acoela, nor a 'true', ganglionic brain and orthogon, typical for other Platyhelminthes. Expand
SALMFamide2 and serotonin immunoreactivity in the nervous system of some acoels (Xenacoelomorpha)
TLDR
The selective binding properties of a neuropeptide antibody raised in echinoderms (SALMFamide2, or S2), and a commercial antibody against serotonin (5‐HT) are used to provide additional characters of the acoel nervous system. Expand
Architectonics of the central nervous system of Acoela, Platyhelminthes, and Rotifera
TLDR
Comparison of histochemical and immunocytochemical studies of the CNS in representatives of Acoela, free living and parasitizing Platyhelminthes and Rotifera makes it possible to describe development and complication of the initially primitive Bilateria pleux nervous system. Expand
The nervous and muscular systems in the free-living flatworm Castrella truncata (Rhabdocoela): an immunocytochemical and phalloidin fluorescence study.
TLDR
An immunocytochemical study of the free-living flatworm Castrella truncata (Dalyellioida) has been performed, and staining of the muscular system with TRITC conjugated phalloidin revealed muscle patterns that have not been described previously. Expand
The plastic nervous system of Nemertodermatida
TLDR
High-resolution differential interference contrast microscopy permitted to better visualize some morphological characters of the species studied, such as statocysts, sperm and glands and, in combination with anti-tubulin staining, describe in detail the broom organ in F. apelti. Expand
Organization of the orthogon – main and minor nerve cords
TLDR
The central nervous system of flatworms has been regarded as comprised of the bilobed brain, the longitudinal cords and the connecting transverse commissures forming a so called orthogon, but support for the special status of the main nerve cords has been obtained from studies of the neuroanatomy of Catenulida, Macrostomida, Proseriata, Tricladida and Lecithoepitheliata. Expand
The nervous system of Isodiametra pulchra (Acoela) with a discussion on the neuroanatomy of the Xenacoelomorpha and its evolutionary implications
TLDR
The nervous system of Isodiametra pulchra consists of an insunk, bilobed brain, a peripheral part for perception and innervation of the smooth body-wall musculature as well as tracts and motor neurons that together with pseudostriated inner muscles are responsible for steering and quick movements. Expand
An immunocytochemical and ultrastructural study of the nervous and muscular systems of Xenoturbella westbladi (Bilateria inc. sed.)
TLDR
The results are compatible with the hypothesis of Xenoturbella westbladi forming a sister taxon to Bilateria and the organisation of the nervous system appears very simple. Expand

The Central and Peripheral Nervous System of Acoela (Plathelminthes). An Electron Microscopical Study
TLDR
The fine structure of the nerve cells and the neuropile in the brain of acoels and the peripheral nervous system and the synapses have been studied and the nervous system of acOels should no longer be considered as primitive. Expand

IR to 5-HT antiserum (anti-5-HT) observed in the NS of all the investigated flatworms confirm the importance of this bioamine, which may have appeared early in platyhelminth evolution. Expand

TLDR
The ultrastructural studies of neuronal cells indicating that a common secretory cell type containing dense-core vesicles is archaic and a likely progenitor cell type for conventional neurons of advanced flatworms and that an independent evolution of synaptic structures and glial cells has occurred inside the flatworm taxon are dealt with.

TLDR
It is suggested that parasitic platyhelminthes appeared early in the evolution of the group and form a sister group to a still-unresolved clade made by Nemertodermatida, Lecithoepitheliata, Prolecithophora, Proseriata and Rhabdocoela, and that Seriata is paraphyletic. Expand
