The concept of 'neuroplasticity' has revolutionized our understanding of the human brain. Historically, scientists believed that the adult brain was largely fixed in structure and function after a critical period in childhood. However, research over the past few decades has demonstrated that the brain remains highly adaptable throughout life, capable of reorganizing neural pathways in response to learning, experience, or injury. This adaptability is not unlimited; it is influenced by factors such as age, the intensity of stimulation, and the nature of the task. For instance, individuals who lose their sight often show enhanced auditory or tactile processing, as the brain reallocates resources from the visual cortex to other sensory modalities. Such findings have profound implications for rehabilitation, education, and the treatment of neurological disorders, suggesting that targeted interventions can harness plasticity to promote recovery and cognitive enhancement.

It is constrained by certain factors like age and stimulation intensity.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
