The concept of neuroplasticity has revolutionized our understanding of the human brain. Historically, scientists believed that the adult brain was structurally fixed, with neural circuits becoming immutable after a critical period in childhood. However, recent research demonstrates that the brain retains a remarkable capacity for reorganization throughout life. This adaptability is driven by synaptic strengthening, the formation of new neural connections, and even the generation of neurons in specific regions like the hippocampus. Such changes are most pronounced in response to learning, environmental enrichment, and recovery from injury. For instance, individuals who lose their sight often show enhanced tactile and auditory processing, as the visual cortex is recruited for other sensory modalities. While the extent of plasticity diminishes with age, it never ceases entirely. This finding has profound implications for rehabilitation and education, suggesting that targeted interventions can harness the brain's inherent flexibility to improve cognitive function and motor skills.
❓ Según el pasaje, ¿cuál de las siguientes afirmaciones refleja mejor la comprensión actual de la neuroplasticidad?
A. El cerebro adulto es en gran medida inmutable después de la infancia.
B. La neuroplasticidad ocurre solo en respuesta a una lesión cerebral grave.
C. El cerebro puede reorganizarse a lo largo de la vida, aunque la capacidad puede disminuir con la edad.
D. La actividad de la corteza visual está permanentemente fijada y no puede ser alterada por la pérdida sensorial.
✅ 正确答案
The brain can reorganize itself throughout life, although the capacity may decline with age.
