How the Brain Turns Down the Volume on Your Noisy Body

Dr. Sawtell, who is also professor of neuroscience at Columbia University Medical Center, and his team have largely tackled this issue using an unusual model system — a species of electric fish, called the elephantnose fish, from Africa that both generates and senses electricity. Their studies have revealed important insights into how circuits in the brains of these fish distinguish behaviorall...
