Adult neurogenesis in the decapod crustacean brain: a hematopoietic connection?
New neurons are produced and integrated into circuits in the adult brains of many organisms, including crustaceans. In some crustacean species, the first‐generation neuronal precursors reside in a
Insights into the genetic regulatory network underlying neurogenesis in the parthenogenetic marbled crayfish Procambarus virginalis
TLDR
An in situ hybridization protocol is established for the crayfish Procambarus virginalis and embryonic expression patterns of a suite of key genes, encompassing three SoxB group transcription factors, two achaete–scute homologs, a Snail family member, the differentiation determinants Prospero and Brain tumor, and the neuron marker Elav are studied.
Adult neurogenesis in crayfish: Origin, expansion, and migration of neural progenitor lineages in a pseudostratified neuroepithelium
TLDR
An extended DPS model is proposed that emphasizes structural similarities to pseudostratified neuroepithelia in other arthropods and vertebrates and includes hemocyte integration and intrinsic cell proliferation to synergistically counteract niche cell pool depletion during the animal's lifespan.
Neurogenesis in the central olfactory pathway of adult decapod crustaceans: development of the neurogenic niche in the brains of procambarid crayfish
TLDR
The data suggest that the LPZ and MPZ are largely responsible for the production of new neurons in the early post-embryonic stages, and that the neurogenic niche in the beginning plays a subordinate role, however, as the neuroblasts in the proliferation zones disappear during earlyPost-Embryonic life, the neuronal precursors in the niche gradually become the dominant and only mechanism for the generation of new neuron in the adult brain.
The ‘Ventral Organs’ of Pycnogonida (Arthropoda) Are Neurogenic Niches of Late Embryonic and Post-Embryonic Nervous System Development
TLDR
The pycnogonid cluster-stream-systems show striking similarities to the life-long neurogenic system of decapod crustaceans, and due to their close vicinity to glomerulus-like neuropils, it is considered their possible involvement in post-embryonic (perhaps even adult) replenishment of olfactory neurons – as in decapods.
Cell proliferation in the central nervous system of an adult semiterrestrial crab.
TLDR
A neurogenic niche is described in the central olfactory system of the crab Ucides cordatus and two types of glial cells in the deutocerebrum are identified, based on different markers, using two glial markers.
Adult Neurogenesis and Neurogenic Plasticity in the Zebrafish Brain
TLDR
The robust neurogenic capacity of the adult zebrafish brain is taken advantage to examine differences in forebrain and sensory neurogenic niches in regards to cytoarchitectural organization, neurogenic plasticity, and regulation.
Hematopoietic-derived cells as potential neural precursors in adult neurogenesis
TLDR
A strong positive correlation was found between the Numbers of circulating hemocytes immediately before sacrifice and the numbers of cells in the neurogenic niche following HPT ablation, demonstrating a close and dynamic relationship between hematopoiesis and adult neurogenesis in the crayfish brain.
Neurons and Glia Cells in Marine Invertebrates: An Update
TLDR

Neurogenesis in the developing crab brain: postembryonic generation of neurons persists beyond metamorphosis.
TLDR
Neurogenesis in the brain of laboratory-reared larvae of the spider crab Hyas araneus is recorded and results are discussed with regard to reports on neuronal proliferation during adult life in insects and rodents.
Adult neurogenesis: A common strategy across diverse species
TLDR
Evidence is provided suggesting that, as in the higher vertebrates, the precursor cells maintaining adult neurogenesis in the crayfish Procambarus clarkii are glial cells, and extensive structural and functional parallels suggest a common strategy for the generation of new neurons in adult brains.
The common properties of neurogenesis in the adult brain: from invertebrates to vertebrates.
From Embryo to Adult: Persistent Neurogenesis and Apoptotic Cell Death Shape the Lobster Deutocerebrum
TLDR
The results indicate that, in juvenile and adult lobsters, birth and death of olfactory interneurons occur in parallel, suggesting a turnover of these cells.
Patterns of neurogenesis in the midbrain of embryonic lobsters differ from proliferation in the insect and the crustacean ventral nerve cord.
TLDR
Quantitative and temporal analyses suggest that the clearing time for BrdU is 2-3 days in lobster embryos, and that the sequence of proliferative events in the midbrain is significantly different from the stereotypical pattern for the generation of neurons in the ventral nerve cord ganglia of insects and crustaceans.
Neurogenesis in the thoracic neuromeres of two crustaceans with different types of metamorphic development
TLDR
The divergent temporal patterns of neurogenesis in the two crustacean species can be correlated with differences in larval life style and in the degree of maturation of the thoracic legs during metamorphic development.
Newborn cells in the adult crayfish brain differentiate into distinct neuronal types.
TLDR
The results show that large numbers of adult-generated cells in cluster 10 differentiate into neurons expressing the neuropeptide crustacean-SIFamide, and provide the first evidence that adult neurogenesis is also a characteristic feature of the optic neuropils of decapod crustaceans.
Adult neurogenesis in the crayfish brain: Proliferation, migration, and possible origin of precursor cells
TLDR
Preliminary evidence is presented for an association between vascular cells and the niche precursors, which may relate to the life‐long growth and maintenance of the crustacean neurogenic niche.
Adult neurogenesis in a moth brain
TLDR
It is hypothesized that the newly born neurons could play a role in the central nervous plasticity of olfactory processing in the adult moth A. ipsilon and that adult neurogenesis could occur in the moth brain using 5‐bromo‐2′‐deoxyuridine injections on newly born and sexually mature moths.
