  1. PSYCH JOURNAL 10/10/2013 • How do you experience pain? Do injuries cause you intense pain or mild pain? • Do you think your mind has a role in controlling pain? Have you ever been able to control your pain by thinking a certain way? Explain..

  2. Skin Senses

  3. How we feel • Nerve endings are stimulated by contact or temperature.

  4. Brain processes touch in the somatosensory cortex (parietal lobe). • Sensitivity is greater where more receptor nerves exist (faces, tongues, hands)

  5. Our sense of touch • Research is new, there is still a great deal of information that is not known to scientists. (ex: why people are ticklish) • What we do know: • Four basic skin senses: touch, warmth, cold, and pain.

  6. Pain • Pain serves as a warning system • Pain differs from other senses – when the stimulus producing the pain is removed, the pain continues. • Pain can be generated as a result of sensory information or can be generated from the brain itself

  7. Gate-Control Theory of Pain • Thoughts and feelings can influence our reaction to pain. • How does this work?: • Pain impulses must get past a neurological “gate” in the spinal cord. When closed, the “gate” can block pain messages. • Small fibers located on the “gate” are the physical “keys” that can open the “gate”.

  8. Phantom Pain • Person continues to feel pain after a limb (for example) is removed. The Gate-Control theory does not explain this medical phenomenon.

  9. Neuromatrix Theory of Pain • The brain is capable of generating pain on its own • Network of neurons in the brain gives us a sense of our own body • When the network produces an abnormal pattern, pain results • Memories, emotion, and expectations influence pain • Phantom Pain – Abnormal patterns due to lack of sensory stimulation – amputated limbs.
