The cerebellum is a structure in the suprasegmental nervous system classically known for its involvement in motor functions such as motor planning, coordination, and motor learning. However, with scientific advances, other functions of the cerebellum, such as cognitive, emotional, and autonomic processing, have been discovered. Currently, there is a body of evidence demonstrating the involvement of the cerebellum in nociception and pain processing. The aim of this review is to present the current literature on the anatomical, physiological, and functional aspects of the cerebellum in pain processing and suggest functional mechanisms of pain processing based on the cerebellum and its connections with other brain structures. To achieve this, searches were conducted in databases to identify relevant studies on the topic. Studies with relevant data and information were collected and summarized. Current literature demonstrates that the cerebellum receives nociceptive afferents from different pathways and exhibits activity in different regions including the vermis, hemispheres, and deep cerebellar nuclei in pain processing. Through its connections with different brain regions, it is possible that the cerebellum participates in the multidimensional processing of pain, which may make it a potential therapeutic target for pain treatment.
