Transcriptome analysis of the central nervous system of the mollusc Lymnaea stagnalis
BackgroundThe freshwater snail Lymnaea stagnalis (L. stagnalis) has served as a successful model for studies in the field of Neuroscience. However, a serious drawback in the molecular analysis of theExpand

Electrical membrane properties and ionic currents in cultured goldfish gonadotrophs.
The electrical membrane properties and ionic currents of cultured identified goldfish gonadotrophs were characterized using whole-cell patch-clamp recordings. Under current-clamp recordingExpand

Early development of an identified serotonergic neuron in Helisoma trivolvis embryos: serotonin expression, de-expression, and uptake.
In early-stage embryos of Helisoma trivolvis, a bilateral pair of identified neurons (ENC1) express serotonin and project primary descending neurites that ramify in the pedal region of the embryoExpand

Gonadotropin‐releasing hormone neuronal system of the freshwater snails Helisoma trivolvis and Lymnaea stagnalis: Possible involvement in reproduction
Peptides of the gonadotropin‐releasing hormone (GnRH) family are present in neural and nonneural tissues throughout the chordate phylum. Although GnRH peptides have been implicated in nonreproductiveExpand

Characterization and development of rotational behavior in Helisoma embryos: role of endogenous serotonin.
Cilia-driven rotational behavior displayed by embryos of the pond snail Helisoma trivolvis was characterized in terms of its behavioral subcomponents, developmental changes, and response to exogenousExpand

Serotonergic sensory-motor neurons mediate a behavioral response to hypoxia in pond snail embryos.
Oxygen (O(2)) is one of the most important environmental factors that affects both physiological processes and development of aerobic animals, yet little is known about the neural mechanism of O(2)Expand

Presence and biological activity of a GnRH‐like factor in the nervous system of Helisoma trivoluis
Gonadotropin‐releasing hormone (GnRH) constitutes a family of neuropeptides found throughout the vertebrates. Although a GnRH‐like peptide has also been isolated from yeast (α‐mating factor), theExpand

Effect of serotonin on ciliary beating and intracellular calcium concentration in identified populations of embryonic ciliary cells
SUMMARY Embryos of the pond snail Helisoma trivolvis express three known subtypes of ciliary cells on the surface of the embryo early in development: pedal, dorsolateral and scattered single ciliaryExpand

Identification, molecular structure and expression of two cloned serotonin receptors from the pond snail, Helisoma trivolvis
SUMMARY Helisoma trivolvis has served as a model system to study the functions of serotonin (5-HT) from cellular, developmental, physiological and behavioural perspectives. To further explore theExpand

Coordinated development of identified serotonergic neurons and their target ciliary cells in Helisoma trivolvis embryos
Embryonic neuron C1s (ENC1s) are bilateral serotonergic neurons that function as cilioexcitatory motor neurons in embryonic development of the pond snail, Helisoma trivolvis. Recent experimentsExpand
