Diversity and Biosynthetic Potential of Culturable Microbes Associated with Toxic Marine Animals
Marine Drugs, 2013 Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported.

The Chemistry and Biology of the Tetrodotoxin Natural Product Family
Angewandte Chemie International Edition, Volume 64, Issue 35, August 25, 2025.Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.

Functional Roles and Circuitry in an Inhibitory Pathway to Feeding Command Neurones in Pleurobranchaea [PDF]
Journal of Experimental Biology, 1984 ABSTRACT The paracerebral neurones (PCNs) of the brain of Pleurobranchaea californica serve a command role in the initiation of feeding behaviour (Gillette, Kovac & Davis, 1978). The PCNs are synaptically excited by food stimuli applied to the oral veil of hungry, naive animals.

Activity recorded from the statocyst nerve of Pleurobranchaea californica during rotation and at different tilts [PDF]
Comparative Biochemistry and Physiology Part A: Physiology, 1972 1. 1. The statocysts of Pleurobranchaea californica lie lateral to the pedal ganglia. The thirteen receptor cells communicate with the cerebro-pleural ganglion via the thirteen axons of the statocyst nerve. 2. 2. Each unit in the statocyst nerve of Pleurobranchaea responds over a limited range of positions. 3. 3. Receptor adaptation is slow.

Selective Recruitment of Interganglionic Interneurones During Different Motor Patterns in Pleurobranchaea [PDF]
Journal of Experimental Biology, 1983 ABSTRACT The buccal and anterior head structures of the mollusc, Pleurobranchaea, participate in several types of behaviour which are generated largely by rhythmic activity produced in the brain and buccal ganglia. This paper examines the neuronal mechanisms (1) by which motor output from these ganglia is coordinated, and, (2) which ...

Neuronal Substrates of Behavioral Hierarchies and Associative Learning inPleurobranchaea [PDF]
American Zoologist, 1974 The carnivorous marine mollusc Pleurobranchaea californica exhibits two forms of behavioral plasticity: behavioral choice and associative learning. Behavioral choice is the selection of one behavioral act in preference to another, as dictated by a behavioral hierarchy. In Pleurobranchaea , feeding behavior occupies a relatively dominant position in the

Selective prey avoidance learning in the predatory sea-slugPleurobranchaea californica [PDF]
Journal of Experimental Biology, 2013 SummaryPredator-prey interactions involving aposematic signaling, where predators learn the warning cues of well-defended prey, are clear examples of cost-benefit decisions in foraging animals. However, knowledge of the selectivity of predator learning and the natural conditions where it occurs is lacking for those foragers simpler in brain and body ...

Co‐regulation of cAMP‐activated Na+ current by Ca2+ in neurones of the mollusc Pleurobranchaea. [PDF]
The Journal of Physiology, 1993 1. The cAMP‐gated Na+ current (INa, cAMP) was studied in axotomized neurons of the pedal ganglion of the sea slug Pleurobranchaea. INa, cAMP responses were elicited by iontophoretic injection of cAMP and recorded in voltage clamp. 2. The current‐voltage relation for INa, cAMP was flat between ‐90 and ‐50 mV, but declined steeply with depolarization ...
