“Orcas and some other large whales have spindle neurons in their brains. These are cells that process emotion humans thought existed only in apes and us. Spindle neurons have been called the cells that make us human. They're the part of the brain that deals with complex emotions like love, guilt, grief and even embarrassment. Since these are the cells that allow us to feel deeply, isn't it likely they do the same for orcas?” — Mark Leiren-Young
