Localization of octopaminergic neurones in insects.
Octopamine-immunoreactive neurons in the central nervous system of the cricket, Gryllus bimaculatus
TLDR
The distribution of octopamine-immunoreactive neurons is described using whole-mount preparations of all central ganglia of the cricket, Gryllus bimaculatus to discuss possible neurohemal releasing sites forOctopamine.
Patterns of serotonin-immunoreactive neurons in the central nervous system of the earthworm Lumbricus terrestris L.
TLDR
Segmental variations in the pattern and number of serotonin-immunoreactive somata in the different body regions are discussed on the background of known developmental mechanisms that result in metameric neuronal populations in annelids and arthropods.
Patterns of serotonin-immunoreactive neurons in the central nervous system of the earthworm Lumbricus terrestris L.
TLDR
The distribution and morphology of serotonin-immunoreactive cells are compared with previous observations, based on pattern analysis of primary catecholamines and indolamines with the use of a formaldehyde-induced fluorescence technique.
Putative neurohemal areas in the peripheral nervous system of an insect, Gryllus bimaculatus, revealed by immunocytochemistry
TLDR
An extensive system of varicose fibers has been detected throughout the nerves of all neuromeres, except for nerve 2 of the prothoracic ganglion, indicating neurosecretory storage and release of neuroactive compounds.
The distribution of neurones immunoreactive for β-tyrosine hydroxylase, dopamine and serotonin in the ventral nerve cord of the cricket, Gryllus bimaculatus
TLDR
The cellular localization of the biogenic amines dopamine and serotonin was investigated in the ventral nerve cord of the cricket, Gryllus bimaculatus, using antisera raised against dopamine, β-tyrosine hydroxylase and serotonin to find dopamine- and serotonin-immunoreactive elements in efferent cells and afferent elements.
The diverse layout of amine-containing systems in the ventral cord of an insect.
Comparisons of neuron types containing either 5-HT, dopamine, histamine or octopamine as identified by light and electron microscopic immunocytochemistry for the ventral nerve cord in the cricket,
Multisegmental cobalt filling of the dorsal giant fibers in the nervous system of the earthworm, Lumbricus terrestris
TLDR
The anatomical organization of the two dorsal giant fiber systems of the earthworm Lumbricus terrestris is demonstrated in whole mounts and serial-section reconstructions based on backfillings of the ventral nerve cord with cobalt chloride and may correlate with functional electrotonic coupling.
