homeostasis

The return of the disequilibrated organ systems of the body to steady states or dynamic stability is known as homeostasis.

人们身体里失调的器官系统恢复到稳定的或动态稳定状态的过程被称为体内平衡。

In order to maintain this homeostasis, the brain deploys motivations such as pain, hunger, thirst and fear, as well the complementary pleasures of food, water, sex and safety.

为了保持这种体内平衡，大脑对我们会施加如疼痛、饥渴和恐惧等刺激，同样也会在得到食物、水、性满足和安全感时发出喜悦的信号。
