Pain: why it hurts and how the brain creates it

The microcourse reveals the physiology of pain through the work of nociceptors, the role of the spinal cord, and the contribution of the cortex. You will learn how the brain interprets signals and why, in chronic conditions, pain can intensify or form without a direct threat. The course will help you distinguish an acute response from persistent patterns associated with nervous system learning and stress. After completing it, you will be able to explain your own sensations, recognize mechanisms that amplify pain, and discuss them more accurately with specialists.
