Neural regeneration in the chick retina

Progress in Retinal and Eye Research, 2005
In 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, 1991
The 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 ...

Extracellular Matrix in Neural Plasticity and Regeneration

Cellular and Molecular Neurobiology, 2020
The 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.

Timing neural development and regeneration

Current Opinion in Neurobiology
Regulation of neural progenitor temporal identity is critical to control the chronological order of cell birth and generation of cell diversity in the developing central nervous system (CNS). Single-cell RNA sequencing studies have identified transcriptionally distinct early and late temporal identity states in mammalian neural progenitors in multiple ...

IC for neural signal regeneration

2008 9th International Conference on Solid-State and Integrated-Circuit Technology, 2008
Based 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.

The Phenomenon of Neural Regeneration

1996
Following 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,

A regenerating spiking neural network

Neural Networks, 2005
Due 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.

Neural Modulation of Regenerating Adrenal Transplants

Endocrine Research, 2000
In addition to control of adrenal cortical steroidogenesis by adrenocorticotropic hormone (ACTH) and angiotensin 11, the intact rat adrenal gland is extensively innervated by a variety of nerve fibers that have been implicated in modulating adrenal cortical function (reviewed in 1).

IMPORTANCE OF NEURAL FIBROBLASTS IN THE REGENERATION OF NERVE

Archives of Neurology And Psychiatry, 1946
It IS generally agreed that the regeneration of peripheral nerve is accomplished by the regrowth of axis-cylinders in close relation to the remnants of the Schwann cells of the degenerated nerve. Whether the Schwann bands form a medium favoring active growth or provide simply a passive linear path without obstruction is still debated.

Regeneration as an application of gastropod neural plasticity

Microscopy Research and Technique, 2000
Gastropod research is providing many insights into mechanisms of neural regeneration. These observations were made possible by the pioneering work of individuals who described the nervous systems of gastropods, mapped prominent neurons and determined their roles and connections, and developed the techniques for culturing them.
