剑桥研究发现,大脑发育分五个阶段进行,关键转变发生在9岁、32岁、66岁和83岁,挑战了20年代大脑成熟期结束的概念。 A Cambridge study finds brain development occurs in five stages, with key shifts at ages 9, 32, 66, and 83, challenging the notion that brain maturity ends in the 20s.

剑桥大学的一项研究分析来自3 800人的MRI扫描,查明了整个生命期的五个不同的大脑发育阶段,关键的转折点是9岁、32岁、66岁和83岁。 A University of Cambridge study analyzing MRI scans from 3,800 people has identified five distinct brain development phases across the lifespan, with key turning points at ages 9, 32, 66, and 83. 研究表明,大脑结构是分阶段演变的:幼年期的快速增长和接线,32岁时的继续完善,66岁前稳定的成人阶段,66岁后与老龄化有关的逐步重组,83岁后进一步衰落。 The research reveals that brain structure evolves in stages: rapid growth and wiring in early life, continued refinement through age 32, a stable adult phase until 66, gradual reorganization linked to aging after 66, and further decline after 83. 研究结果挑战了大脑成熟期在20年代中期结束的概念,表明认知和结构变化延伸到30年代初,而大脑效率的峰值晚于先前的想象。 The findings challenge the notion that brain maturity ends in the mid-20s, showing cognitive and structural changes extend into the early 30s and that brain efficiency peaks later than previously thought.
