Genetic Tools for the Analysis of Drosophila Stomatogastric Nervous System Development
The transgenic lines described offer the ability to specifically manipulate the migration of SNS precursors and will allow the modeling and in-depth analysis of neuronal migration in ENS disorders such as Hirschsprung’s disease.
Anatomy of the stomatogastric nervous system associated with the foregut in Drosophila melanogaster and Calliphora vicina third instar larvae
The extensive conformity of the SNS of both species suggests functional parallels and future electrophysiological studies of the motor circuits in the S NS of Drosophila will profit from parallel studies ofThe homologous but more accessible structures in Calliphora.
Neuropeptides associated with the regulation of feeding in insects.
Tip cell‐derived RTK signaling initiates cell movements in the Drosophila stomatogastric nervous system anlage
It is shown that RTK signaling mediated by the Drosophila homolog of the epidermal growth factor receptor, DER, plays a key role in two consecutive steps during early SNS development and participates in adjusting the range of Notch‐dependent lateral inhibition during tip cell selection.

Despite important differences between the ENS of vertebrates and invertebrates, common features in their programs of neurogenesis, migration, and differentiation suggest that these relatively simple preparations may provide insights into similar developmental processes in more complex systems.

Current data are presented in a comparative view that contributes to the understanding of the role of the STNS in arthropod behaviour and sheds light on the question of homology of the stomatogastric nervous system among the differentArthropod groups.
Neural substrate and allatostatin-like innervation of the gut of Locusta migratoria.
Embryonic differentiation of serotonin‐containing neurons in the enteric nervous system of the locust (Locusta migratoria)
This study followed the anatomy of the serotonergic system throughout embryonic development to provide the initial step for future investigation of potential morphoregulatory functions of serotonin during ENS development.


Embryonic development of the stomatogastric nervous system in Drosophila
Using several cell‐specific markers, the pattern of proliferation, morphogenesis, and neuronal differentiation of the Drosophila larval stomatogastric nervous system (SNS) was analyzed and it was found that recurrent nerve and frontal connectives are pioneered by small subpopulations of early differentiating stomatography neurons that most likely derive from among the dSNSPs and i SNSPs.
Origins of the insect enteric nervous system: differentiation of the enteric ganglia from a neurogenic epithelium.
Observations indicate that the differentiation of the enteric ganglia in Manduca involves an unusual combination of features seen during the formation of other regions of the nervous system and, as such, constitutes a distinct program of neurogenesis.
Proneural and neurogenic genes control specification and Morphogenesis of stomatogastric nerve cell precursors in Drosophila.
The results presented in this paper show that the neurogenic and proneural genes are expressed and required during all phases of SNS development to control the number, pattern, and structural characteristics of the SNSP subpopulations.
Origins, migration and differentiation of glial cells in the insect enteric nervous system from a discrete set of glial precursors
It is shown that prior to the completion of neurogenesis, an additional class of precursor cells is generated from the three proliferative zones of the foregut, which gives rise to a distinct population of peripheral glial cells.
Invagination centers within the Drosophila stomatogastric nervous system anlage are positioned by Notch-mediated signaling which is spatially controlled through wingless.
The results suggest that the wingless pathway acts not as an instructive signal, but as a permissive factor which coordinates the spatial activity of morphoregulatory signals within the stomatogastric nervous system anlage.
Neurogenesis in the insect enteric nervous system: generation of premigratory neurons from an epithelial placode.
It is demonstrated that the entire EP cell population is generated from an ectodermal placode that invaginates from the embryonic foregut, indicating that neurogenesis in the insect ENS involves a developmental strategy that is distinct from that seen in the Insect CNS and which resembles the generation of certain cell classes in the vertebrate nervous system.
Stretch Receptors in the Foregut of the Blowfly
Two bipolar neurons are located in a nerve branch connecting the recurrent nerve and foregut of the blowfly Phormia regina and are vital to the regulation of feeding by the fly.
In: Dynamic Biological Networks: The Stomatogastric Nervous System
This work has shown clear parallels with other invertebrate and vertebrate motor systems in the crustacean stomatogastric nervous system, and these parallels are likely to have implications for the design and operation of future nervous systems in crustaceans.
