Sensitisation

Sensitisation (pronunciation: sen-si-ti-za-tion) is a non-associative learning process in which repeated administration of a stimulus results in the progressive amplification of a response. Sensitisation often refers to pain or the amplification of pain responses. It can occur at both the peripheral and central levels of the nervous system.

Etymology

The term "sensitisation" originates from the Latin word "sensitivus", meaning "capable of sensation". It was first used in the medical context in the late 19th century to describe the process of making an organism more sensitive or responsive to a stimulus.
