In this video I go into more detail on pain perception. First I discuss the importance of pain as a signal of danger or harm to the body. Next I explain the two types of nerve fibers which carry different pain messages: A-delta fibers for sharp, intense pains and C-fibers for dull, throbbing pains. I provide a mnemonic for remembering the fiber types and then discuss two other concepts related to pain: gate control theory and referred pain.

Wanna share this:
Why does putting cold water on a skin injury reduce the pain felt?
Putting cold water on a skin injury can help reduce pain for several reasons:
1- Numbness: Cold temperatures can numb the area, making it less sensitive to pain signals. This is similar to how ice is used to numb a part of the body before a procedure.
2- Blood Vessel Constriction: Cold water constricts blood vessels, reducing blood flow to the injured area. This can help slow down bleeding and reduce swelling, both of which can contribute to pain.
3- Inflammation Reduction: Cold therapy can help reduce inflammation, which is often associated with pain and swelling after an injury.
4- Muscle Relaxation: Cold can help relax muscles, which can also contribute to pain relief.
It's important to note that while cold therapy can be helpful for mild injuries, it's not always suitable. For severe injuries or burns, it's best to consult a healthcare professional.
How do painkillers reduce the pain felt?
Painkillers, or analgesics, reduce pain by interfering with the body's pain signaling system.
Here are the primary mechanisms through which they work:
1- Blocking Pain Signals:
Opioids: These drugs bind to opioid receptors in the brain, spinal cord, and other parts of the nervous system. This blocks pain signals from reaching the brain, effectively reducing the perception of pain.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): NSAIDs, such as ibuprofen and aspirin, inhibit the production of prostaglandins, substances that contribute to inflammation and pain. By reducing inflammation, they can also reduce pain.
2-Altering Pain Perception:
Acetaminophen: While the exact mechanism is not fully understood, acetaminophen is believed to act on the central nervous system, altering the perception of pain without affecting inflammation.
3-Addressing Underlying Causes:
Some painkillers, such as those used to treat migraine headaches, target specific underlying causes of pain. For example, triptans used for migraines can constrict blood vessels in the brain, which is thought to be involved in migraine attacks.
It's important to note that while painkillers can be effective in managing pain, they may not address the underlying cause of the pain. It's always best to consult with a healthcare professional for proper diagnosis and treatment.
Thank you so much sir for a fruitful session......
I am currently doing my written assignment in Health Psychology and I have been researching for hours to understand pain perception, but this video definitely helped me a lot compared to what I found. Thank you for this, sir!
You're welcome, glad I could help!
Confusing made simple! Thank-you!
Glad to hear that!

Wow! I'm really enjoying these lectures. Definitely going to buy your book. Thank you
Glad you're enjoying them and thanks for the support!
I think another example of gate control theory can be when you use heat on the painful area. This stimulates more thermoreceptors and inhibits the pain signal. Please correct me if im wrong.
I don't think thermoreceptors are directly included in reducing pain in gate-control theory (which focuses on nerve fibers for touch, pressure, & vibration) but may still relate to reducing pain through other mechanisms
@@PsychExamReview Yes that's what I had a confusion about. Anyways, thanks for the reply :)
Thank u so much
You're welcome!
Prof. Croyaer do you advise creating notes/making notes while watching these lectures? I usually scribble in a erasable board ( is it useful?) but then I forget sometimes and end up skipping some points either I feel drowsy or feel saturated. I generally complete a topic playlist and then read the book viz. Baron or notes which I have. Kindly guide.
I think it really depends on what your goal is and what you want to get from the videos.
If you're watching them as a supplement to a course or class then you may just want to focus on taking notes for any terms or content that has also appeared in your class. A research example that isn't included in your course or textbook may not be relevant.
If you're doing research or planning a paper, you could just note the names of researchers and studies that you want to look up later for more detail without needing to come back to the video.
Or if you're trying to improve your mastery of the terms and concepts you might just take brief notes on the key terms and concepts so you can quiz yourself later. For example, you might just write "gate control theory" and then see if you can explain it to yourself a few days later, knowing that you can always come back to the video for details you've forgotten or if you aren't sure if you recalled it correctly.
Hope this helps, best of luck in your studies!
Thank you. This explains a lot. I would love to talk to someone in your field of experience because I am a Hypnosis Therapist and helping clients with pain.
Glad it was helpful. I don't have direct experience in this area and I don't practice hypnosis, so I just have a general understanding of some of the research on the use of hypnosis for pain management (I'm not a specialist in this area). It does seem to be effective for some types of pain, but there are ethical limitations to what can be done in these kinds of studies (types of pain that can be induced, etc.). There is also difficulty in understanding the mechanisms as a number of things could be related to reductions in the experience of pain. Is it due to relaxation techniques, trust and the relationship with the hypnotist/therapist, cognitive biases and expectations about pain intensity, an improved sense of control, etc. and these provide a number of interesting areas to explore in order to understand this better.
