Pain - When Does It Hurt?While pain is no longer considered to be an exclusively human experience, we struggle to agree on which animals suffer from it. Yet if we are to provide appropriate care and welfare for the animals we interact with, we need to have a workable definition of animal pain and a way of determining which animals experience the hurt generated by pain processes. To date, studies in animals have relied on the definitions created to describe human pain, but with our uniquely complex nervous system this presents problems when we try to translate pain processes to animals. Pain is recognized as having two distinct phases; first an unconscious set of reactions, mostly reflex responses, followed by a conscious awareness of the emotions and discomfort. While it is clear that that first phase is observed throughout much of the animal kingdom, the second stage is limited to animals with emotional states. Recent advances in our understanding of the neural processes that underlie emotions as well as empirical evidence of empathy and changes in cognition associated with pain suggest that we now need to review and revise the criteria used to define animal pain. With this more refined approach, we can then start to explore which animals are aware of a negative emotional state induced by pain. My overarching goal is to devise a framework that will allow us to determine which animals experience the negative emotional effects associated with pain.

What is Pain and Why Does it Hurt?
In 1961 Julia Child published a cookery book titled "Mastering the Art of French Cooking". Its publication led to a veritable revolution in the way that mainstream America both prepared and cooked food. On page 221 of this now iconic book, she describes how to cook Lobster Thermidor.
3 live lobsters , 2 pounds each,
3 cups dry white wine
2 cups water,
1 large onion , thinly sliced,
1 medium carrot , thinly sliced,
1 stalk celery , thinly sliced,
1 bay leaf,
6 peppercorns... etc.
Directions: Simmer wine, water, vegetables, herbs, and seasonings in the kettle for 15 minutes. Then bring to the boil and add the live lobsters. Cover and boil for about 20 minutes...
Would you be comfortable putting three live lobsters into a pot of boiling water? If not, why not - what bothers you?
Pain is a negative sensation that most of us try to avoid. It is a subjective experience, we can describe it to others, but only you can experience your pain. When it comes to animal pain, however, we move into a much more difficult area. It might seem plausible that mammals and birds feel pain, but what about fish? They are so alien and live in such a different environment - do they feel pain? And if you are willing to accept that a fish feels pain, then what about lobsters? Could you follow Julia Childs recipe for Lobster Thermidor and feel good about the dish?
In my talk, I will discuss why pain is such a difficult process to understand, why we find it hard to agree on which animals feel it, and why being able to make this distinction matters. I will use fish as a "hard case" example, and I will propose a framework of criteria that might allow us to compare pain processes across different animal groups to help elucidate which animals really feel hurt by their pain.
