That's the brain influencing the cephalic phase of gastric regulation again, by sending extra fight or flight signals to the stomach.

这是大脑通过向胃发送额外的战斗或逃跑信号，再次影响胃调节的头阶段。

The cephalic phase is the one ruled by your brain, and it kicks in when you first see, smell, taste, or even think about food.

头部阶段是由你的大脑控制的阶段，当你第一次看到、闻到、品尝甚至想到食物时，它就开始了。

If I happen to be super-full, or not feeling well, or somebody puts a pile of squid eyeballs in front of me, the cephalic phase isn't gonna happen.

如果我碰巧超级饱，或者感觉不舒服，或者有人在我面前放了一堆鱿鱼眼球，头期不会发生。
