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

A novel DTI technique used on the preserved brains of two dolphins that died after stranding shows 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 are known about how their brains function, so they have remained relatively mysterious. The method for using DTI on a non-living brain was developed relatively recently and had previously only been used for research on deceased humans, primates and rats. There are probably multiple areas in the dolphin brain associated with auditory information, and the neural pathways look similar to those of a bat.
