Pain Modulation | Gate Control & Endogenous Opioid Mechanisms [TENS/IFC]

The video tutorial explains the gate theory of pain perception, emphasizing that pain is a brain perception, not a peripheral occurrence. It details the spinothalamic tract and the roles of first, second, and third order neurons in conveying pain information. The tutorial discusses inhibitory interneurons and their function in modulating pain through inhibition. It also covers different types of nerve fibers, such as A delta, C, and A beta, and their roles in pain perception. Finally, the video explores the endogenous opioid mechanism, highlighting how the brain's natural opioids help reduce pain perception.
