Document Summary

Poking (a non-noxious stimulus) could hurt if you have a sunburn: mechanical allodynia. If you slap, it may indeed have been a pain stimulus before a sunburn. But if you have a sunburn, you will go through the roof: mechanical hyperalgesia. Showering with sunburn: thermal allodynia (you could have thermal hyperalgesia too) Paper that suggests that chronic pain may indeed have a purpose. In a lab, they had a bunch of squid and eventually let some bass in. Prof is not going to go into detail wants us to figure it out ourselves. Under normal circumstances, a little more than 75% of squid survive. If you injure a squid (cut off a leg or an arm: this (cid:449)as(cid:374)"t good fo(cid:396) the s(cid:395)uid, more of them got eaten. Turns out that more of them died if they were injured but not in pain.
