Question

What is neuron proliferation?

1) The process of creating new neurons
2) The process of destroying neurons
3) The process of transmitting signals between neurons
4) The process of repairing damaged neurons

Answer 1

Neuron proliferation, or neurogenesis, is the creation of new neurons from undifferentiated neural stem cells in the brain, even occurring to a limited extent in adults.

Step-by-step explanation:

Neuron proliferation refers to the process of creating new neurons. This process is more formally known as neurogenesis, and it involves the division of undifferentiated neural stem cells that are found throughout the brain to produce new neurons. Initially, it was believed that new neurons could not be formed after the brain was fully developed, implying that the number of neurons was fixed after birth. Recent studies, however, have shown that neurogenesis does occur in the adult brain, although its extent is not largely understood and is not thought to be very significant in humans.
