sorry, wouldn't all fit in one post lol anyways probably good to put in the description so people can copy them in their notes or follow through more easily. Great video! :)

From peripheral sites, pain signals are transported to dorsal horn of the spinal cord. Here they synapse with interneurons, that is, the pain signals are transferred from the nociceptors to the interneurons.

Cell axons in the dorsal horn give rise to spinal thalamic and other ascending tracts that carry the signals upward from the spinal cord. Interneurons carry pain signals to the thalamus and midbrain where they are then transmitted via neurons to the cortex, the frontal lobe and the limbic system.

The actions of the cortex, the frontal lobe and the limbic system contribute to the overall perception of the pain and determines its texture and intensity, giving it an emotional impact; linking it to memories and ultimately giving it meaning.

Chronic pain is more than just prolonged acute pain. As pain signals are repeatedly generated, neuropathways can undergo physiochemical changes known as remodelling that makes them hypersensitive to the pain signals; can make the signals more intense and more localised.
Snnahzz 4 months ago
If chronic pain goes untreated, the pain signals eventually become embedded in the central nervous system just like a painful memory. The central nervous system in effect, learns to have pain. These signals become a distressing, disabling message, constantly signalling the patient about an injury that really belongs in the past.

@jordanpasek search for Lorimer Mosely or David Butler. They both have some YouTube videos as well. The notion of a "pain pathway" perpetuates the myth that pain occurs in the periphery and is transmitted to the brain. " Nociception is neither sufficient nor necessary for the experience of pain" that's from Butler and Mosely "Explain Pain".

Hi. Where did this video come from? I'd love to use it for a presntation I'm doing. Can I use it and use my own voiceover?
