神经元与大脑结构

解释神经元如何以电化学脉冲的形式通过突触传递信号，描述大脑的组织方式（各脑叶及其功能、负责情绪的边缘系统），并解释神经可塑性——为什么学习和练习会在物理层面改变大脑结构——同时联系视错觉，说明大脑是在构建现实而非被动记录现实。

Explain how neurons transmit signals as electrochemical impulses across synapses, describe how the brain is organised (lobes and functions, limbic system for emotion), and explain neuroplasticity — why learning and practice physically change brain structure — connecting to optical illusions as evidence that the brain constructs reality rather than passively recording it

学习证据 / Evidence

• 描述神经元之间的信号传递路径：电脉冲沿轴突传导，神经递质穿过突触，在下一个神经元中产生新的冲动。
• 说出大脑皮层四个脑叶（额叶、顶叶、颞叶、枕叶）的名称，并说明各自的一项功能。
• 解释神经可塑性：重复使用的神经通路会变得更强、更快——这是学习和技能发展的生物学机制。

• Describes the neuron-to-neuron signal pathway: electrical impulse travels along axon, neurotransmitter crosses the synapse, new impulse begins in the next neuron
• Names the four lobes of the cerebral cortex (frontal, parietal, temporal, occipital) and gives one function for each
• Explains neuroplasticity: repeated neural pathways become stronger and faster — this is the biological mechanism of learning and skill development

评估问题 / Assessment

如果{{name}}被问到为什么长期练习钢琴或足球等技能会越来越熟练，ta能否解释大脑中实际发生的物理变化——并说明“大脑自我重塑”是什么意思？

If {{name}} was asked why practising a skill like piano or football makes you better over time, could they explain what's actually happening physically in the brain — and describe what it means to say the brain 'rewires itself'?
