Investigating Diet as the Source of Tetrodotoxin in Pleurobranchaea maculata [PDF]
Marine Drugs, 2013 The origin of tetrodotoxin (TTX) is highly debated; researchers have postulated either an endogenous or exogenous source with the host accumulating TTX symbiotically or via food chain transmission.

Toxins, 2015 Tetrodotoxin (TTX) is a potent neurotoxin found in the tissues of many taxonomically diverse organisms. Its origin has been the topic of much debate, with suggestions including endogenous production, acquisition through diet, and symbiotic bacterial ...

Neuromodulatory control of a goal-directed decision. [PDF]
PLoS ONE, 2014 Many cost-benefit decisions reduce to simple choices between approach or avoidance (or active disregard) to salient stimuli. Physiologically, critical factors in such decisions are modulators of the homeostatic neural networks that bias decision ...

Coordination of Locomotion by Serotonergic Neurons in the Predatory Gastropod Pleurobranchaea californica. [PDF]
J Neurosci, 2023 Similar design characterizes neuronal networks for goal-directed motor control across the complex, segmented vertebrates, insects, and polychaete annelids with jointed appendages. Evidence is lacking for whether this design evolved independently in those lineages, in parallel with segmentation and appendages, or could have been present in a soft-bodied

Complete mitochondrial genome sequence of <i>Pleurobranchaea novaezealandiae</i> and <i>Pleurobranchaea</i> sp. [PDF]
Mitochondrial DNA B Resour, 2016 The complete mitochondrial genome sequences of Pleurobranchaea novaezealandiae and Pleurobranchaea sp. are first described and analyzed in this study. It is 14,531 bp and 14,709 bp in length, respectively. The base composition of the genome with A + T bias are 66.41% and 68.36%.

Neurochemical and neuroanatomical identification of central pattern generator neuron homologues in Nudipleura molluscs. [PDF]
PLoS ONE, 2012 Certain invertebrate neurons can be identified by their behavioral functions. However, evolutionary divergence can cause some species to not display particular behaviors, thereby making it impossible to use physiological characteristics related to those ...

Comprehensive Reviews in Food Science and Food Safety, Volume 21, Issue 1, Page 719-737, January 2022., 2022 Abstract Tetrodotoxins (TTXs) are a group of potent neurotoxins named after the Tetraodontidae fish family (pufferfish). TTXs have been reported in several animal taxa, both terrestrial and marine. The ingestion of TTX‐contaminated flesh can cause serious neurotoxic symptomatology and can eventually lead to death.

A Core Circuit Module for Cost/Benefit Decision
Frontiers in Neuroscience, 2012 A simple circuit for cost-benefit decision derived from behavioral and neural studies of the predatory sea-slug Pleurobranchaea may closely resemble that upon which the more complex valuation and decision processes of the social vertebrates are built ...

Tetrodotoxin Poisoning Due to Pufferfish and Gastropods, and Their Intoxication Mechanism
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 Marine pufferfish generally contain a large amount of tetrodotoxin (TTX) in their skin and viscera, and have caused many incidences of food poisoning, especially in Japan. Edible species and body tissues of pufferfish, as well as their allowable fishing areas, are therefore clearly stipulated in Japan, but still 2 to 3 people die every year due to ...
