记忆是怎样被“巩固”的?

How are memories 'consolidated'?

新记忆先在海马体形成短期痕迹,睡眠中通过反复回放逐步转移到大脑皮层,转为可长期保存的记忆。
New memories first form a short-term trace in the hippocampus, then during sleep are replayed and gradually shifted to the cortex for long-term storage.

偏头痛为什么常伴搏动性头痛和畏光?

Why do migraines often bring pulsing pain and light sensitivity?

偏头痛涉及脑膜血管与三叉神经的异常激活以及炎症介质释放,使痛觉敏感并放大光、声刺激。
Migraine involves abnormal activation of meningeal vessels and the trigeminal nerve with inflammatory messengers, heightening pain and amplifying light and sound.

为什么摸到烫的东西会马上把手缩回来?

Why do we pull our hand back from something hot?

这是身体的快速保护反应,神经一瞬间把“烫”的消息送回去,让手弹开,免得被烫伤。
It's a fast safety reflex - nerves instantly send the 'hot!' message back so your hand flips away before you get burned.
