  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. Brain transplant - Wikipedia

    en.wikipedia.org/wiki/Brain_transplant

    In 1982, Dr. Dorothy T. Krieger, chief of endocrinology at Mount Sinai Medical Center in New York City, achieved success with a partial brain transplant in mice. [8]In 1998, a team of surgeons from the University of Pittsburgh Medical Center attempted to transplant a group of brain cells to Alma Cerasini, who had suffered a severe stroke that caused the loss of mobility in her right limbs as ...

  4. 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.

  5. 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]

  6. Regeneration in humans - Wikipedia

    en.wikipedia.org/wiki/Regeneration_in_humans

    Skin tissue can be regenerated in vivo or in vitro. Other organs and body parts that have been procured to regenerate include: penis, fats, vagina, brain tissue, thymus, and a scaled down human heart. One goal of scientists is to induce full regeneration in more human organs. There are various techniques that can induce regeneration.

  7. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    In vertebrates, the majority of neurons belong to the central nervous system, but some reside in peripheral ganglia, and many sensory neurons are situated in sensory organs such as the retina and cochlea. Axons may bundle into nerve fascicles that make up the nerves in the peripheral nervous system (like strands of wire that make up a cable).

  8. Isolated brain - Wikipedia

    en.wikipedia.org/wiki/Isolated_brain

    1963 – Robert J. White isolated the brain from one monkey and attached it to the circulatory system of another animal. [11] 1993 – Rodolfo Llinás captured the whole brain of a guinea-pig in a fluidic profusion system in vitro which survived for around 8 hours and indicates that field potentials were very similar to those described in vivo ...

  9. Brain cell - Wikipedia

    They can only function in collaboration with other neurons and interneurons in a neural circuit. [1] There are an estimated 100 billion neurons in the human brain. [1] Neurons are polarised cells that are specialised for the conduction of action potentials also called nerve impulses. [1] They can also synthesise membrane and protein.
