Which pain theory confirmed the existence of thermo-sensors?

The correct answer relates to the intensive theory, which emphasizes the role of specific sensory receptors, including thermo-sensors. This theory is based on the understanding that different types of nociceptors are responsible for detecting varying stimuli, including temperature changes. Essentially, it proposes that pain perception can be differentiated based on the type and intensity of the stimulus, with thermo-sensors specifically responding to thermal stimuli that can cause sensations of pain.

In contrast, stimulation theory focuses more on the direct relationship between stimulus intensity and pain perception without specifically addressing the role of temperature receptors. Pattern theory, on the other hand, suggests that pain is perceived based on patterns of neural activity rather than dedicated pain receptors. Lastly, gate control theory introduces the concept of a "gate" mechanism in the spinal cord that modulates pain perception based on competing stimuli and is not solely focused on the presence of thermo-sensors. Understanding the emphasis of these various theories helps clarify why intensive theory is directly linked to the existence of thermo-sensors.
