Introduction to Neuroscience 2: Lecture 6, Pain and Temperature

This is part 2 of the somatosensation lectures. In this lecture, I describe how pain and temperature information is sensed in the skin, including how noxious chemicals and sensed by the same receptors that process temperature. I discuss how pain information goes through the nervous system, and how that differs from touch. Last, we learn about ascending and descending regulation of pain.

The audio gets a little loud on a couple of slides. I had to re-record some slides because the audio was lost in the original file, and I used a much better microphone to do that. Sorry about that!
