Neural Regeneration: Lessons from Regenerating and Non-regenerating Systems
Molecular Neurobiology, 2012One only needs to see a salamander regrowing a lost limb to become fascinated by regeneration. However, the lack of robust axonal regeneration models for which good cellular and molecular tools exist has hampered progress in the field. Nevertheless, the nervous system has been revealed to be an excellent model to investigate regeneration.

Emerging roles for semaphorins in neural regeneration
Brain Research Reviews, 2001Progressive axon outgrowth during neural development contrasts with the failure of regenerative neurite growth in the mature mammalian central nervous system (CNS). During neuroembryogenesis, spatiotemporal patterns of repellent and attractant activities in the vicinity of the growth cone favor neurite outgrowth.

Neural regeneration in gastropod molluscs
Progress in Neurobiology, 1995Snails recover function following a variety of neural injuries. They grow new tentacles with associated tentacle ganglia, selectively reinnervate peripheral targets, repair central connections and may even replace lost neurons and ganglia. The plasticity revealed in their responses to neural injury is an extreme expression of the adaptability observed ...

How the Neural Retina Regenerates
2000The rules that govern cellular behavior during development and regeneration of tissues are complex and enigmatic, but substantial progress is being made toward understanding the molecular basis of proliferation and differentiation. Although most of the recent mechanistic insights have been gained from studies of embryonic development, the capacity of ...

Neural regeneration in the chick retina
Progress in Retinal and Eye Research, 2005In warm-blooded vertebrates, possibilities for retinal regeneration have recently become reality with the discovery of neural stem cells in the mature eye. A number of different cellular sources of neural stem cells have been identified. These sources include stem cells at the retinal margin, pigmented cells in the ciliary body and iris, non-pigmented ...

Advances in neural regeneration.
Annals of the Royal Australasian College of Dental Surgeons, 1991The familiar concept of the inability of injured neurones in the mammalian central nervous system to regenerate has been deep-rooted in the minds of neurologists since the time of Ramon y Cajal. However, modern research techniques and novel experimental manipulations have begun to reveal the existence of a robust potential for axonal regrowth even in ...

IC for neural signal regeneration
2008 9th International Conference on Solid-State and Integrated-Circuit Technology, 2008Based on the 4-channels neural signal regeneration system which was realized by using discrete devices and successfully used for in-vivo experiments of rats and rabbits, an integrated circuit (IC) with 6-channels of neural signal regeneration has been designed and realized in CSMC?s 0.6 ?m CMOS technology.

Extracellular Matrix in Neural Plasticity and Regeneration
Cellular and Molecular Neurobiology, 2020The extracellular matrix (ECM) is a fundamental component of biological tissues. The ECM in the central nervous system (CNS) is unique in both composition and function. Functions such as learning, memory, synaptogenesis, and plasticity are regulated by numerous ECM molecules.

A regenerating spiking neural network
Neural Networks, 2005Due to their distributed architecture, artificial neural networks often show a graceful performance degradation to the loss of few units or connections. Living systems also display an additional source of fault-tolerance obtained through distributed processes of self-healing: defective components are actively regenerated.

The Phenomenon of Neural Regeneration
1996Following neural injury, the complex sequence of events leading to neural regeneration will not be undertaken unless survival in the short term is assured. For most species to survive injury to the central nervous system (CNS), neural control of homeostatic functions must remain intact, although some very simple animals, such as flatworms, ribbon worms,
