Neurons in the superior colliculus of echo-locating bats respond to ultrasonic signals.
Using conventional electrophysiological techniques, we demonstrate that neurons in the superior colliculus of the big brown bat (Eptesicus fuscus) respond to ultrasonic signals. Most response properties of these neurons are very similar to neurons of the inferior colliculus in the same bat.
