Control of feeding motor output by paracerebral neurons in brain of Pleurobranchaea californica
Journal of Neurophysiology, 19821. A population of interneurons that control feeding behavior in the mollusk Pleurobranchaea has been analyzed by dye injection and intracellular stimulation/recording in whole animals and reduced preparations. The population consists of 12-16 somata distributed in two bilaterally symmetrical groups on the anterior edge of the cerebropleural ganglion (

Pleurobranchaea egg-laying hormone: Localization and partial purification
Journal of Comparative Physiology ? B, 19771. Egg-laying behavior in the gastropodPleurobranchaea californica is a stereotyped sequence of events lasting several hours and culminating in the extrusion of eggs and their attachment to the substrate (Fig. 1). A hormone that causes egg laying has been localized in the two pedal ganglia by means of bioassay (Table 1).

Semisynthesis of labdane diterpene metabolites from the nudibranch Pleurobranchaea meckelii
Tetrahedron, 2007Abstract Two isomeric labdane aldehyde metabolites ( 1 and 2 ), first isolated from the skin of the Notaspidean nudibranch Pleurobranchaea meckelii , were synthesized in six steps from manool in 19 and 6% overall isolated yields, respectively.

Muscarinic antagonist enhances one-trial food-aversion learning in the mollusc Pleurobranchaea
Brain Research Bulletin, 1988One hour before training, in two replicate studies on the sea slug Pleurobranchaea californica, all animals (N = 114) received body-cavity injections of scopolamine, oxotremorine, or the equivalent volume of the saline/seawater vehicle that was used to inject the drugs.

Diet of the invasive sea slug Pleurobranchaea maculata in Patagonian coastal waters
New Zealand Journal of Zoology, 2018ABSTRACT High densities of the invasive sea slug, Pleurobranchaea maculata , have been detected on the Argentinean coast, but studies on the species’ adaptation have been absent until now. Stomach contents of P.

In situ accumulation of tetrodotoxin in non-toxic Pleurobranchaea maculata (Opisthobranchia)
Aquatic Sciences, 2016Tetrodotoxin (TTX) is a highly potent neurotoxin targeting voltage gated sodium channels. It is found in numerous phyla, including both marine and terrestrial taxa, however, its origin is a topic of considerable debate. The aim of this study was to investigate the origin of TTX in the Opisthobranch Pleurobranchaea maculata using in situ experimentation.

Microsatellite development for a tetrodotoxin-containing sea slug (Pleurobranchaea maculata)
Biochemical Systematics and Ecology, 2014Abstract Using 454 pyrosequencing data, 24 polymorphic microsatellite markers were identified for the grey side-gilled sea slug, Pleurobranchaea maculata . The grey side-gilled sea slug is found throughout the western and south Pacific and is known to contain high concentrations of tetrodotoxin.

Brain Research, 1985
The neural manifestations of food avoidance learning in the mollusc, Pleurobranchaea, survive the surgical reduction of the preparation to the nearly isolated brain. These manifestations include increased synaptic inhibition and reduced synaptic excitation of the phasic paracerebral feeding command interneurons (PCps) in the brain in response to food ...

Comparative study of histamine immunoreactivity in nervous systems of Aplysia and Pleurobranchaea
Journal of Comparative Neurology, 1990AbstractThe distribution of histamine in the nervous system of the marine molluscs Aplysia californica and Pleurobranchaea californica was studied by using a newly available immunohistochemical localization technique and specific antiserum against histamine‐protein conjugate.

Higher order neurons in buccal ganglia of Pleurobranchaea elicit vomiting motor activity
Journal of Neurophysiology, 1983The buccal mass of the gastropod Pleurobranchaea is used during a regurgitation response that consists of a writhing phase interrupted by brief periodic bouts of a vomiting phase (17, 20). During transitions from writhing to vomiting, specific changes occur in the motor pattern (19, 20).
