  2. Neuroregeneration - Wikipedia

    en.wikipedia.org/wiki/Neuroregeneration

    The nervous system is divided by neurologists into two parts: the central nervous system (which consists of the brain and spinal cord) and the peripheral nervous system (which consists of cranial and spinal nerves along with their associated ganglia). While the peripheral nervous system has an intrinsic ability for repair and regeneration, the ...

  3. Neural stem cell - Wikipedia

    en.wikipedia.org/wiki/Neural_stem_cell

    The neuroblasts form tight chains and migrate towards the specified site of cell damage to repair or replace neural cells. One example is a neuroblast migrating towards the olfactory bulb to differentiate into periglomercular or granule neurons which have a radial migration pattern rather than a tangential one. [8]

  4. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system. They are located in the brain and spinal cord and help to receive and conduct impulses.

  5. Adult neurogenesis - Wikipedia

    en.wikipedia.org/wiki/Adult_neurogenesis

    The axolotl is less commonly used than other vertebrates, but is still a classical model for examining regeneration and neurogenesis. Though the axolotl has made its place in biomedical research in terms of limb regeneration, [19] [20] the model organism has displayed a robust ability to generate new neurons following damage.

  6. Neurogenesis - Wikipedia

    en.wikipedia.org/wiki/Neurogenesis

    First, this may generate a subclass of neuronal progenitors called intermediate neuronal precursors (INP)s, which will divide one or more times to produce neurons. Alternatively, daughter neurons may be produced directly. Neurons do not immediately form neural circuits through the growth of axons and dendrites.

  7. Endogenous regeneration - Wikipedia

    en.wikipedia.org/wiki/Endogenous_regeneration

    Endogenous regeneration in the brain is the ability of cells to engage in the repair and regeneration process. While the brain has a limited capacity for regeneration, endogenous neural stem cells, as well as numerous pro-regenerative molecules, can participate in replacing and repairing damaged or diseased neurons and glial cells.

    Tomiko Itooka, who became the world's oldest living person, died last week at age 116. Brazilian nun Inah Canabarro Lucas is now the new world's oldest person.

  9. Neuronal cell cycle - Wikipedia

    en.wikipedia.org/wiki/Neuronal_cell_cycle

    These neurons re-enter the cell cycle as they travel to the ganglion cell layer when they are activated by p75NTR. These neurons are unable to enter mitosis and are stuck in a 4C DNA content state. Cell cycle re-entry by p75NTR is not dependent on Cdk4/6 (Morillo et al., 2012) and, therefore, differs from other cell types that re-enter the cell ...
