To understand this process you can refer to scientific and medical explanations. I won’t go into details here.

To put it simply, when external information is transmitted to the corresponding nerves to produce stimulation, it is called sensory stimulation. The source of this external information can be reading books, newspapers, watching movies and TV, listening to music, talking to people, eating and drinking, etc.

However, the current usage of this word is more inclined to violent stimulation, causing people to have strong emotions and feelings. For example, suspicion, trembling, horror, fear, sexual desire, excitement, passion, etc.
