Abstract
Serotonin is a widely studied modulator of neural plasticity. Here we investigate the effect of fluoxetine, a selective serotonin reuptake inhibitor, on short-term, peripheral nociceptive plasticity in the neurologically complex invertebrate, octopus. After crush injury to isolated mantle (body wall) tissue, application of 10 nM fluoxetine increased spontaneous firing in crushed preparations, but had a minimal effect on mechanosensory sensitization. Effects largely did not persist after washout. We suggest that transiently elevated, endogenous serotonin may help promote initiation of longer-term plasticity of nociceptive afferents and drive immediate and spontaneous behaviors aimed at protecting wounds and escaping dangerous situations.
期刊介绍：
Invertebrate Neurosciences publishes peer-reviewed original articles, reviews and technical reports describing recent advances in the field of invertebrate neuroscience. The journal reports on research that exploits the simplicity and experimental tractability of the invertebrate preparations to underpin fundamental advances in neuroscience. Articles published in Invertebrate Neurosciences serve to highlight properties of signalling in the invertebrate nervous system that may be exploited in the field of antiparisitics, molluscicides and insecticides. Aspects of particular interest include:
Functional analysis of the invertebrate nervous system;
Molecular neuropharmacology and toxicology;
Neurogenetics and genomics;
Functional anatomy;
Neurodevelopment;
Neuronal networks;
Molecular and cellular mechanisms of behavior and behavioural plasticity.
