Is nitric oxide (NO) produced by invertebrate neurones?
NADPH-diaphorase (NADPHd) is known to be identical to nitric oxide (NO) synthase in the mammalian nervous system, and is therefore used as a marker of NO-producing neurones. Using the histochemical… Expand
Serotonin-and FMRFamide-immunoreactive nerve elements in the chiton Lepidopleurus asellus (Mollusca, Polyplacophora)
The distribution of serotonin-like and FMRFamide-like immunoreactive (5HT-ir and FMRFa-ir, respectively) neurons in the nervous system of the chiton Lepidopleurus asellus (Mollusca, Polyplacophora)… Expand
The fine structure of the procerebrum of pulmonate molluscs, Helix and Limax.
Neuronal perikarya of the procerebrum of Helix and Limax are generally naked and lie side by side. The cell mass contains large numbers of axosomatic and axoaxonic synapses represented by boutons of… Expand
Effects of Serotonergic and Opioidergic Drugs on Escape Behaviors and Social Status of Male Crickets
Abstract We examined the effects of selective serotonin depletion and opioid ligands on social rank and related escape behavior of the cricket Gryllus bimaculatus. Establishment of social rank in a… Expand

The pleural interneuron PlB is a white neuron in the pleural ganglion of the snail Lymnaea. We test the hypothesis that it inhibits neurons at all levels of the feeding system, using a combination of… Expand
Immunolabeled neuroactive substances in the osphradium of the pond snail Lymnaea stagnalis
The osphradium of molluscs is assumed to be a sensory organ. The present investigation in Lymnaea stagnalis has established two ultrastructurally different types of dendrites in the sensory… Expand
Patterns of enkephalin immunolabeling in the pulmonate snailCepaea nemoralis and related molluscs
In the land pulmonate snail Cepaea nemoralis, immunocytochemical localization of methionine- and leucine-enkephalin-like substances was demonstrated in specific populations of brain neurons.… Expand
Complex avoidance behaviour and its neurochemical regulation in the land snail Cepaea nemoralis.
1. In hot plate experiments, the pulmonate land snail Cepaea nemoralis displays a biphasic passive/active avoidance behaviour composed of retraction and subsequent searching mediated by antagonistic… Expand
Effects of dopamine antagonists on snail locomotion
Dopamine antagonists which affect the ergometrine-sensitive type of dopamine receptors produce characteristic motor disorders in a land snail,Helix pomatia L.

The generally accepted synaptic concept is an idealization based on two major assumptions essential for a system of neurone to be orderly organized: firstly, specificity of anatomical connections… Expand
