Which of the following statements is true?
A)Injured or damaged neurons in the central nervous system can never regenerate.
B)No new neurons are produced in the central nervous system after infancy.
C)Neurogenesis occurs in the spinal cord but not in the brain.
D)Recent research suggests that stem cells in the brain may be able to generate new neurons throughout life.

Question

Quizplus · Accepted Answer

Recent research has shown that stem cells in the brain are capable of generating new neurons throughout life, a process called neurogenesis. While the ability of neurons to regenerate in the central nervous system is limited, the discovery of neurogenesis has opened up new possibilities for treating brain injuries and degenerative diseases. Option A is incorrect because damaged neurons can regenerate to a limited extent under certain conditions. Option B is incorrect because neurogenesis continues to occur in certain regions of the brain, including the hippocampus, throughout adulthood. Option C is incorrect because neurogenesis has been observed in both the spinal cord and the brain.
