Echo-Ranging Neurons in the Inferior Colliculus of Bats

Nobuo Suga 1

1 Department of Biology, Washington University, St. Louis, Missouri

Bats measure the distance to an object in terms of the time lag between their outgoing orientation sounds and the returning echo. For measurement of the time lag, the latency of response of a neuron to a stimulus must be nearly constant regardless of the stimulus amplitude and envelope. Otherwise, a large error would be introduced into the measurement. Bats have neurons that are specialized for echo ranging.
