当异常半球中的神经元在成熟之前经历过多的细胞分裂时，就会发生这种罕见的疾病，即大脑一侧长得比另一侧大得多。

The rare disorder, in which one side of the brain grows substantially larger than the other, occurs when neurons in the abnormal hemisphere undergo too many cell divisions before they mature.

For every new word you learn in your English lesson, every problem you solve in maths, every new song you learn to sing, a neuronal network grows in your brain and the brain changes.
