Different Proctolin Neurons Elicit Distinct Motor Patterns from a Multifunctional Neuronal Network
TLDR
Modulatory neurons that share a peptide transmitter can elicit distinct motor patterns from a common target network and only one of them (MCN1) also elicits a gastric mill rhythm.
Crustacean neuropeptides
TLDR
The basic biology of crustacean neuropeptides is reviewed, methodologies currently driving their discovery are discussed, an overview of the known families is provided, and recent data on their control of physiology and behavior is summarized.
De Novo Assembly of a Transcriptome for Calanus finmarchicus (Crustacea, Copepoda) – The Dominant Zooplankter of the North Atlantic Ocean
TLDR
The de novo transcriptome presented here represents a new resource for acquiring physiological data on a key copepod crustacean, Calanus finmarchicus, and is the first report of multiple NaV1 genes in a protostome.
Hormone complement of the Cancer productus sinus gland and pericardial organ: An anatomical and mass spectrometric investigation
TLDR
The results show that diverse and unique complements of hormones, including many previously unknown peptides, are present in the SG and PO of C. productus, and sets the stage for future biochemical and physiological studies of these molecules.
Two novel tachykinin-related peptides from the nervous system of the crab Cancer borealis.
TLDR
Two novel peptides from the C. borealis nervous system are isolate and characterize that show strong amino acid sequence identity to the invertebrate tachykinin-related peptide (TRP) family and are named CabTRP Ia and Ib, respectively, which are myoactive in the cockroach hindgut muscle contraction bioassay.
Identification, tissue distribution and orexigenic activity of neuropeptide F (NPF) in penaeid shrimp
TLDR
The data suggest that NPF is present in both the nervous system and midgut of penaeid shrimp, functioning, at least in part, as a powerful orexigenic agent.
GABA and responses to GABA in the stomatogastric ganglion of the crab Cancer borealis.
TLDR
GABA is found in projection neurons to the crab STG and can evoke both excitatory and inhibitory actions on STG neurons, which is helpful in determining which actions of neurons are evoked by GABA.
Cloning and differential expression of two β‐pigment‐dispersing hormone (β‐PDH) isoforms in the crab Cancer productus: Evidence for authentic β‐PDH as a local neurotransmitter and β‐PDH II as a
TLDR
The hypothesis that duplication and subsequent mutation of a common neuropeptide gene may underlie the evolution of two differentially distributed transcripts that serve distinct physiological roles in the nervous system of C. productus is supported.
Stereotyped neuropil branching of an identified stomatogastric motor neuron
TLDR
Evidence is presented that, for at least one intrinsic neuron type, the ventricular dilator (VD) neuron, a highly organized and stereotyped branching structure exists within the stomatogastric neuropil.
