Top row of three brains includes two baleen whale specimens at the ends and the larger brain of a sperm whale in the middle where blocks of cerebral cortex have been removed from the surface for study. The bottom two specimens include, on the left, a brain from the bottlenose dolphin (paler color results from preservation treatment) and, on the right, a human brain for comparison.
