Scientists discover new pain-sensing organ in the skin

The video discusses the traditional understanding of mechanical pain perception through nerve cell endings in the epidermis and introduces a new discovery by researchers at Sweden's Karolinska Institute. They found a sensory organ, the nociceptive glio-neural complex, between the skin's layers, which is sensitive to mechanical stimuli. The organ's functionality was tested by genetically modifying mice to respond to light stimulation, resulting in pain-indicative behaviors.
