Mechanoreceptive and Nociceptive Responses in the Central Nervous System of Goldfish (Carassius auratus) and Trout (Oncorhynchus mykiss)

This study presents novel data on telencephalic activity in fish after noxious stimulation and demonstrates the potential for pain perception in lower vertebrates. Not only is this of an evolutionary significance, but it also adds to the controversial argument about whether fish perceive pain.
