It was a firm belief in science for a long time that brain cells did not regenerate. However, new studies on the brains of primates show that the brain does regenerate and reproduce brain cells.
the answer is yes damaged brain cells can be replaced.
The brain's ability to act and react in ever-changing ways is known, in the scientific community, as "neuroplasticity." This special characteristic allows the brain's estimated 100 billion nerve cells, also called neurons (aka "gray matter"), to constantly lay down new pathways for neural communication and to rearrange existing ones throughout life, thereby aiding the processes of learning, memory, and adaptation through experience. Neuroplasticity is the saving grace of the damaged or disabled brain; without it, lost functions could never be regained, nor could disabled processes ever hope to be improved. Plasticity allows the brain to rebuild the connections that, because of trauma, disease, or genetic misfortune, have resulted in decreased abilities. It also allows us to compensate for irreparably damaged or dysfunctional neural pathways by strengthening or rerouting our remaining ones.
Most of the cells in your body can not reproduce. Only one type of cell in your body can reproduce, stem cells. Depending on where stem cells are, they turn into different types of cells. A stem cell in your muscle will turn into a muscle cell. Stem cells in your liver turn into liver cells. There are some stem cells in your brain. They turn into brain cells. You do your thinking with brain cells. Stem cells are undifferentiated. They can not think. They must turn into specialized cells before they can work.
as far as i think, yes because people are lossing and gaining them every second and if you dont get new ones you would very quickly become brain dead and die
A better question you should be asking why can't ALL brain cells reproduce? Try reading up on 'neurogenesis'
Healthy individuals lose around 9,000 brain cells daily. Certain drugs such as ketamine, nitrous oxide, and inhalants cause brain cell death at almost thirty times the normal rate. Alcohol plays a role in brain cell death, but not as large a part as drugs.
damaged fingerprints, which cant be detected by any machine.
b/c your brain would cause you to lose consciousness and then normal breathing would start to resume.
Why can't certain cells,like bacteria,get to be the size of a small fish
Two things a cell must have are DNA and Ribosomes. Purposes DNA: Without DNA cells can't reproduce or the anythin really. Its like the brain of the cell , without it, you cant function properly. Ribosomes: They are a "must-have" organelle (the name for an organ in a cell) for protein production , the cell's food. Without the cell will "starve" and die.
there are some cells in the body that after the are produced once, they can no longer reproduce. These cells are known as cells in the quiescent stage. They are permanantly in G0 phase.
no. Is cant be replaced if u hav damaged it. Even if once d CD is opened tearing its seel it cant be replaced or money can not be returned.
you cant gain brain cells, just reading will use more than just sitting about
No your lungs cant be replaced because you ll die before you can.

no but your brain does control your heart. also, without a heart your brain cant bunction, and without a brain your heart cant function. hope i helped
if the retina is damaged - medical science cant repair that kind of damage
both any cancer, even after full treatment and remission has a tendency to metastasis. the favourite sites being the brain, bone and lung; due to spread of the cancer cells through the blood.
you cant
you cant
It cant be replaced!
i just asked my teacher and no they cant as they have no proof
