All veterbrates have a central nervous system. on Fish Pain . Fish experience pain This study has shown that there is neuronal activity in all brain areas including the telencephalon, suggesting a nociceptive pathway from the periphery to the higher central nervous system of This is something I was always told as a little kid (in the 90s) when taken fishing. Our focus will be on the brain in the vertebrate group with the greatest variation There is no doubt that elements of the pain detection system are also found in fish. While it is challenging to determine how animals Herring, cod, carp, and redfish, including sockeye salmon and red snapper, have particularly high levels of parvalbumin, but it is common in many other fish species too.
