Study reveals dolphin brains evolved for echolocation

A new study reveals how dolphin brains have evolved to support echolocation, the process by which they use sound to navigate and hunt. The research compares brain networks in echolocating dolphins and non-echolocating baleen whales. Researchers found that dolphins have stronger connections between the midbrain and cerebellum, suggesting the cerebellum plays a key role in integrating auditory information with the production of echolocation clicks. This contrasts with previous assumptions. The study utilized advanced brain imaging techniques on deceased cetaceans, offering insights into the unique neural adaptations supporting dolphin echolocation, which is more akin to "touching" with sound.
