  2. Neuroregeneration - Wikipedia

    en.wikipedia.org/wiki/Neuroregeneration

    Guillain–Barré syndrome – nerve damage. Neuroregeneration in the peripheral nervous system (PNS) occurs to a significant degree. [5] [6] After an injury to the axon, peripheral neurons activate a variety of signaling pathways which turn on pro-growth genes, leading to reformation of a functional growth cone and regeneration.

  3. Neuronal cell cycle - Wikipedia

    en.wikipedia.org/wiki/Neuronal_cell_cycle

    In cerebellar granule cells and cortical neurons, E2F1 can trigger neuronal apoptosis through activation of Bax/caspase-3 and the induction of the Cdk1/FOXO1/Bad pathway (Giovanni et al., 2000). The downregulation of p130/E2F4 (a complex which has been shown to maintain the post mitotic nature of neurons) induces neuronal apoptosis by ...

  4. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    Neurons such as Purkinje cells in the cerebellum can have over 1000 dendritic branches, making connections with tens of thousands of other cells; other neurons, such as the magnocellular neurons of the supraoptic nucleus, have only one or two dendrites, each of which receives thousands of synapses.

  5. Llinás's law - Wikipedia

    en.wikipedia.org/wiki/Llinás's_law

    A neuron of a given kind (e.g. a thalamic cell) cannot be functionally replaced by one of another type (e.g. an inferior ollivary cell) even if their synaptic connectivity and the type of neurotransmitter outputs are identical. (The difference is that the intrinsic electrophysiological properties of thalamic cells are extraordinarily different ...

  7. 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.

  8. Neurogenesis - Wikipedia

    en.wikipedia.org/wiki/Neurogenesis

    These findings suggested that these newly made cells can mature into more practical and useful neurons in the adult mammalian brain. [33] Recent studies confirm that microglia , the resident immune cell of the brain, establish direct contacts with the cell bodies of developing neurons, and through these connections, regulate neurogenesis ...

  9. Permanent cell - Wikipedia

    en.wikipedia.org/wiki/Permanent_cell

    Disease and virology studies can use permanent cells to maintain cell count and accurately quantify the effects of vaccines. [1] Some embryology studies also use permanent cells to avoid harvesting embryonic cells from pregnant animals; since the cells are permanent, they may be harvested at a later age when an animal is fully developed.
