The distribution of histamine-immunoreactive neurons in the ventral nerve cord of the cricket, Gryllus bimaculatus
TLDR
The wide-spread innervation of all neuromeres by HA-ir interneurons and the identification of possible neurohemal release sites suggest a general role of HA as a neuroactive substance, including neuromodulatory and neurohormonal functions.
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.
