TLDR
The stainings revealed that the neuroarchitecture of the arcuate body is characterized by several distinct layers some of which comprise nerve terminals that are organized in columnar, palisade-like arrays.About:

Selective neuronal staining in tardigrades and onychophorans provides insights into the evolution of segmental ganglia in panarthropods

TL;DR: The organisation of the nervous system in three tardigrade species using antisera directed against tyrosinated and acetylated tubulin, the amine transmitter serotonin, and the invertebrate neuropeptides FMRFamide, allatostatin and perisulfakinin shows correspondences that support the homology of segmental ganglia in tardsigrades and arthropods.

Deep metazoan phylogeny : the backbone of the tree of life : new insights from analyses of molecules, morphology, and theory of data analysis
TL;DR: This work provides the most comprehensive overview available of the state of the art in this exciting field of evolutionary research with a focus on nervous systems.

Architectural Principles and Evolution of the Arthropod Central Nervous System
TL;DR: It is shown that neurobiology is one of the most active fields of arthropod research, and the central nervous system and visual organs of neglected taxa such as Myriapoda have been analyzed with contemporary techniques.

The minute brain of the copepod Tigriopus californicus supports a complex ancestral ground pattern of the tetraconate cerebral nervous systems
TL;DR: The present observations suggest that a suite of morphological characters typifying the Tigriopus brain reflect a ground pattern organization of an ancestral Tetraconata, which possessed an elaborate and structurally differentiated nervous system.

An anterior medial cell population with an apical-organ-like transcriptional profile that pioneers the central nervous system in the centipede Strigamia maritima
Vera S. Hunnekuhl,Michael Akam +1 more
TL;DR: The observations suggest that the arthropod brain retained ancestrally an anterior medial population of neurosecretory cells homologous to those of the apical plate in other invertebrate phyla, but that this cell population has been lost or greatly reduced in insects.

A higher control center of locomotor behavior in the Drosophila brain
R Strauss,M Heisenberg +1 more
TL;DR: Walking in 15 Drosophila mutant strains belonging to eight independent X-linked genes that affect the structure of the central complex is examined, finding that declining walking activity is not an unspecific side effect of structural brain defects, as steady walking is observed in structural mutants of the visual system and mushroom bodies.

Vergleichende Anatomie des Nervensystems der wirbellosen Tiere : unter Berücksichtigung seiner Funktion
TL;DR: The author states that his observations on the eyes and optic ganglia of arthropods afford no evidence of the continuity of neurones, and in the special part each phylum is described in turn, beginning with the Protozoa.

Neuronal architecture of the central complex in Drosophila melanogaster
TL;DR: It is proposed that the central complex of Drosophila melanogaster is an elaboration of the interhemispheric commissure serving the fast exchange of data between the two brain hemispheres in the control of behavioral activity.

Maplike Representation of Celestial E-Vector Orientations in the Brain of an Insect
Stanley Heinze,Uwe Homberg +1 more
TL;DR: A topographic representation of zenithal E-vector orientations underlies the columnar organization of the protocerebral bridge in a locust, which is highly suited to signal head orientation under the open sky.
