First images of dolphin brain circuitry hint at how they sense sound

Neuroscientists have for the first time mapped the sensory and motor systems in the brains of dolphins. Proceedings of the Royal Society B is publishing the results, showing that at least two areas of the dolphin brain are associated with the auditory system, unlike most mammals that primarily process sound in a single area.

"Dolphins are incredibly intelligent, social animals and yet very little is known about how their brains function, so they have remained relatively mysterious,” says Dr. Gregory Berns, faculty member in Neuroscience, and lead author of the study. “We now have the first picture of the entire dolphin brain and all of the white matter connections inside of it."
