He said it is disproved by the fact that birds, which have no neocortex, are generally considered to be creatures that demonstrate consciousness and self-awareness, Balcombe said.

But in his study, Rose highlighted research showing that animals whose brains and cortex were removed demonstrated emotional responses similar to those shown by the fish in Sneddon's experiments. Just as nociception differs from conscious pain, so emotions differ from feelings. Balcombe counters Rose's argument by asserting that the pallium, which is found in the brains of fish, is equivalent to the neocortex. Become a member Login.

Do Fish Feel Pain? The Answer Might Surprise You!
This part of the brain allows a lab rat with arthritis to choose to drink from bad-tasting water containing painkillers instead of sweetened water, which is preferred by rats without the condition. Remove the cerebral hemispheres, and a fish still pretty much acts like a fish, albeit one with no sense of smell. Do it in a human and you get a person in a constant vegetative state. When hooked by fishermen, trout and sharks react in much the same way — by thrashing, darting, and pulling.
And even though trout produce their own internal chemical analgesic, those hormones probably have additional roles besides numbing pain, such as speeding up healing, as they do in humans. It takes a lot of brain power for primates to have even primary consciousness — entry level on the pain scale. The odds are slim that fish can do that with a smaller setup. Both are nociceptor reactions. A big clue to answering the pain question would be if fish would seek analgesic relief from pain if given the chance — if they would self-medicate, like the arthritic rats.
So would observations that differentiate stress from pain behavior. More research into fish brain structures may lead to more definitive answers — even about how all brains work.

New research from the University of Manchester seems to indicate fish can regrow injured brain tissue. Sneddon and her colleagues began their study out of concern for the welfare of animals in commercial fish farms. For his part, Rose thinks a whole lot of energy is wasted discussing fish pain.
This much effort should be made to answer bigger questions of conservation, including water quality, water temperatures, and habitat protection, he says. Rose, J.
