The longitudinal nerve cords (LNC) in Gyrocotyle fimbriata do not change their activity in response to catecholamines but are excited by the amino acids glutamate and aspartate at concentrations less than 10(-5)M. This activity can be blocked by application of 2-amino-4-phosphonobutyrate (APB), an aminergic blocking agent. In situ measurements of fluorescent spectra from LNC neurites have a lambdamax at 513.6 nm. Treatment with HCI shifts the peak to 510 nm. Both glutamate and aspartate… 
Age-dependent changes in fluorescent neurons in the brain of Notoplana acticola, a polyclad flatworm.
TLDR
The presence of a small population of fluorescent cells within the brain of the marine polyclad flatworm Notoplana acticola suggests that the fluorescent substance in the neurons is dopaminergic in nature.

TLDR
The instrumentation and methodology described in the experiment, quantitatively measure the extracellular electrical potentials associated with motor activity and provide highly sensitive objective techniques for studying the effects of antitrematodal compounds and for evaluating P. cervi as a model for neuropharmacological investigations.
GABA in the nervous system of parasitic flatworms.
TLDR
Results indicate that GABAergic neurotransmission may be a potential target for chemotherapy in flatworms too, since several insecticides and antinematodal drugs are thought to interfere with GABA-receptors.
Immunocytochemical localization of glutamate-like immunoreactivity within the nervous system of the cestode Mesocestoides corti and the trematode Fasciola hepatica
TLDR
Immunostaining was widespread in the central (CNS) and peripheral (PNS) nervous systems of both species examined, and glutamate-IR was evident in the innervation of both the oral and the ventral suckers.
Effects of amino acid neurotransmitters on spontaneous muscular activity of the rumen amphistome, Gastrothylax crumenifer.
TLDR
Observations suggested that L-glutamate has an excitatory, whereas GABA and glycine have an inhibitory, effect on the spontaneous muscular activity of G. crumenifer.

The Role of 5-Hydroxytryptamine (5-HT; Serotonin) in Glucose Transport, Intermediary Carbohydrate Metabolism and Helminth Neurobiology
TLDR
5-HT is synthesised in the enterochromaffin cells of the intestinal mucosa of mammals, particularly in the proximal intestine, and appears to be an increase in the rate of carbon flux through the intermediary pathways of carbohydrate metabolism.

Immunocytochemical study on biologically active neurosubstances in daughter sporocysts and cercariae of Trichobilharzia ocellata and Schistosoma mansoni.
TLDR
Trematodes are, together with cestodes, phylogenetically the oldest classes in which glutamate-like material and immunopositivity to a number of neuropeptides isolated from invertebrates has been demonstrated.
Demonstration of intense glutamate-like immunoreactivity in the longitudinal nerve cords of the cestodeHymenolepis diminuta
TLDR
The hypothesis that glutamate is an excitatory neurotransmitter in the platyhelminths is supported, in conjunction with previous studies on glutamate inH.

2-Amino-4-phosphonobutyric acid as a glutamate antagonist on locust muscle
TLDR
The glutamate analogue, DL-2-ammo-4-phosphonobuytyric acid (DL-APB), inhibits the binding of glutamate to ‘receptor-like’ hydrophobic proteolipids isolated from locust muscle and antagonises the excitatory action of glutamate applied iontophoretically to receptors present in the locust Muscle membrane.
THE QUANTITATIVE DISTRIBUTION OF 5‐HYDROXY‐TRYPTAMINE IN THE INVERTEBRATES, ESPECIALLY IN THEIR NERVOUS SYSTEMS *
TLDR
It is clear that 5-HT is found in primitive nervous systems and that its presence in the vertebrate central nervous system is only a recent part of a long phyloenetic history, while some interesting differences between phyla, for example between Arthropoda and Mollusca, and between classes within a phylum, are shown.
2-amino-4-phosphonobutyric acid: a new pharmacological tool for retina research.
TLDR
Intracacellular electrophysiological recordings from the perfused retina-eyecup preparation of the mud-puppy showed that the addition of 2-amino-4-phosphonobutyric acid to the bathing medium blocked all responses in the ON channel but left intact the OFF responses including OFF ganglion cell discharge.

Chemotherapy of parasitic worms: new biochemical strategies.
TLDR
Serotonin receptors are present in several species of parasitic flatworms and appear to participate in the regulation of motility and carbohydrate metabolism, while lysergic acid diethylamide and its 2-bromo derivative are the most potent antagonists.
Effects of putative neurotransmitters on the motor activity of Spirometra mansonoides.
TLDR
5-Hydroxytryptamine (5-HT), epinephrine, and dopamine strongly stimulated the motor activity of larval Spirometra mansonoides and paralyzed the worms.
A METHOD FOR DIFFERENTIATING DOPAMINE FROM NORADRENALINE IN TISSUE SECTIONS BY MICROSPECTROFLUOROMETRY
TLDR
Fluorophores induced from noradrenaline and dopamine in tissue sections by treatment with formaldehyde can be separated by their different behavior upon HCl treatment by using a microspectrofluorometer.
Schistosoma mansoni: identification of chemicals that attract or trap its snail vector, Biomphalaria glabrata.
TLDR
The results permit formulation and testing of controlled-release attractants designed to overcome the repellant effects of slow-release molluscicides, as well as the design of stimulants to be used with no-release poisons.
Identification of chemicals of snail origin that attract Schistosoma mansoni miracidia
TLDR
Biomphalaria glabrata, the molluscan vector of S. mansoni, the important parasite of humans, contributes amino acids to the aqueous environment, and that these, and possibly other substances elicit chemotactic and chemokinetic responses by miracidia of this parasite.
