Dolphin cognitive abilities raise ethical questions, says Emory neuroscientist
Some dolphin brains exhibit features correlated with complex intelligence, she says, including a large expanse of neocortical volume that is more convoluted than our own, extensive insular and cingulated regions, and highly differentiated cellular regions.
"Dolphins are sophisticated, self-aware, highly intelligent beings with individual personalities, autonomy and an inner life. They are vulnerable to tremendous suffering and psychological trauma," Marino says.
