Columbia scientists study ability of fish to recognize self

Scientists from Columbia University are studying fish in order to understand how disorders like tinnitus work in humans. Their findings show that in order to perceive the rest of the world, brains have to first cancel out any noise made by the body itself. By preventing the fish from cancelling out the noises they made, the researchers found that the fish were unable to tell the difference between what was part of their environment and what was caused by themselves, causing a significant disruption to their ability to successfully travel through their surroundings.

Columbia University is a member of NYSERNet’s R&E network.
