The concept of neuroplasticity has revolutionized our understanding of the brain's capacity for change. Historically, it was believed that the adult brain was structurally fixed after a critical period in childhood. However, recent research demonstrates that synaptic connections can be strengthened or weakened throughout life in response to learning and experience. This plasticity is particularly evident in individuals who acquire new skills, such as musicians or bilingual speakers, where cortical reorganization occurs. Moreover, neuroplasticity underlies rehabilitation after brain injury, as undamaged regions can assume functions previously performed by damaged areas. Despite these advances, the extent of plasticity diminishes with age, and the mechanisms governing it remain incompletely understood, prompting ongoing investigation into factors that enhance or inhibit neural adaptation.
❓ According to the passage, which of the following statements is true?
A. A) The adult brain is completely fixed and cannot change after childhood.

C. C) Brain plasticity can aid recovery after injury by allowing other regions to take over lost functions.
D. D) The mechanisms of neuroplasticity are fully understood by scientists.
✅ 正确答案
C) Brain plasticity can aid recovery after injury by allowing other regions to take over lost functions.
